Question 6

What is Dennis' score in Networking?

7.7

8.3

Insufficient data

SOLUTION

Solution : C

Let us take Chirag's score and find out the weightage given for programming and networking. Chirag's scores in Programming and networking are 8 and 6 respectively. Total marks in Technical skills is 7.2 ie,

So the weightage for programming and networking is 3:2.
Solution : Average score of Dennis in Programming $= \frac{6 + 7}{2} = 6.5.$

$\frac{7.1 - 6.5}{x - 7.1} = \frac{2}{3} \Rightarrow x = 8$

Question 7

What are the minimum marks scored by Elizabeth in Interpersonal skills in percentage terms?

33.33%

43%

50%

30%

SOLUTION

Solution : B

For Bharat we know that scores of 5,7 and 6 in different sections result in total score of 6 in Soft skills. So it is the simple average.
Hence total marks for Elizabeth in soft skills $= 8.1 \times 3 = 24.3$
She can score maximum of 10 each in the two sections other than Interpersonal skills. So the minimum marks in interpersonal skills is 24.3-20=4.3 which is 43%

Question 8

What is Elizabeth's total score in the campus recruitment test?

7.3

7.5

7.4

None of these

SOLUTION

Solution : A

From Abay's score we can see that scores of 7.7 and 9.2 in technical and soft skills result in a total score of 8.2.

So the weightage is 2:1. So Elizabeth's total score in technical skills, x is

x=6.9
So, Elizabeth's total score is

t=7.3

Question 9

What is Abhay's score in C++?

8.5

6.6

9.8

SOLUTION

Solution : D

$\frac{7.7 - 6.5}{x - 7.7} = \frac{3}{2} \Rightarrow x = 8.5$ Here x is the average of Java and C++, so score in C++ =9

Question 10

Children are in pursuit of a dog whose leash has broken. "A” is directly behind the dog. "B” is behind "A”. "D” is behind "B”. "C” is ahead of the dog walking down the street in the opposite direction. As the children and dog pass, "C” turns around and joins the pursuit. He runs in behind "B”. "A” runs faster and is alongside the dog on the left. "B” runs faster and is alongside the dog on the right. Which child is directly behind the dog?

SOLUTION

Solution : D

After all the switches were made, "C” is directly behind the dog, "A” is alongside the dog on the left, "B” is alongside the dog on the right, and "D” is behind "C”. Therefore, option (D) is the correct answer choice.

Question 11

Watchman A has worked more night shifts in a row than Watchman B, who has worked five. Watchman C has worked fifteen night shifts in a row, more than Watchman A and Watchman B combined. Watchman D has worked eight night shifts in a row, less than Watchman A. How many night shifts in a row has Watchman A worked?

eight

nine

ten

eleven

SOLUTION

Solution : B

Watchman A has worked more shifts in a row than Watchman D; therefore, Watchman A has worked more than eight shifts. The number of Watchman A's shifts plus the number of Watchman B's shifts (five) cannot equal fifteen or more, the number of Watchman C's shifts. Therefore, Watchman A has worked nine shifts in a row (5 + 9 = 14). Therefore, option (b) is the correct answer choice.

Question 12

How many bronze medals did college R win in these five events?

SOLUTION

Solution : B

Swimming-S, Running-R, Cycling-c, Discus Throw-D and Horse Riding-H
From (i), (v) and (vi), Q won 2 gold medals but not in S or D.
From (iii), T won gold in one from among R or C while T did not win silver in S or D
From (i), S did not win silver in those events in which Q won gold medals. Hence, S did not win any medals in those events.
From (Iv), R won 4 medals and the other colleges won 3 or less medals.
So, the medals won by the remaining 4 colleges are 3, 3, 3 and 2.
T has won 2 medals (i.e., 1 gold and 1 silver (using iii).
P has won 3 medals. So, it must have won 1 gold in silver and 2 bronze in two from among R, C and H.
The gold medals are exhausted as P-1, Q-2, R-1, T-1,
S can win 3 medals: 2 silver and 1 bronze.
Q has won 3 medals: 2 gold among from R, C and H, an 1 bronze.

R won 4 medals: bronze in S, gold in D and 2 silver. There are only three Medal-winning combinations :

None of these

SOLUTION

Solution : C

$\begin{matrix} C o l l e g e s & P & Q & R & S & T P o i n t s & 5 & 7 & 8 & 5 & 5 \end{matrix}$
Thus P,S and T scored 5 points each. Hence, [c].

Question 16

Which year had the lowest turnover to net profit ratio?

2006 - 07

2007 - 08

2008 - 09

2010 - 11

SOLUTION

Solution : D

Approximate Turn overto net profit ratios for various years are:
2006-07 = $\frac{150}{3}$ = 50
2007-08 = $\frac{250}{5}$ = 50
2008-09 = $\frac{200}{5}$ = 40
2009-10 = $\frac{260}{7}$ = 37
2010-11 = $\frac{320}{9}$ = 35

Question 17

In 2007 - 08 if ABC accounted for 7% of industry turnover and the industry turnover saw a growth of 12 % in 2008-09, what was the approximate growth rate ABC's share in industry turnover in 2008-09 over 2007-08?

+5%

-5%

-28.5%

+28.5%

SOLUTION

Solution : C

Total industry turnover in 2008-09 = 250 $\times$ $(\frac{100}{7})$ $\times$ 112 = 4000 Crores.
So percentage share of ABC in 2008-09 = $(\frac{200}{4000})$ $\times$ 100 = 5%
So growth rate = $\frac{5 - 7}{7}$ $\times$ 100 = -28.5%

Question 18

What is the average annual growth rate in net profit from 2006-07 to 2010-11?

25%

50%

75%

100%

SOLUTION

Solution : B

The actual values for net profit for various years are 3,5,4.8,7 and 9. So the average annual growth rate = $\frac{(9 - 3) \times 100}{3 \times 4}$ = 50%

P, Q, R, S, T, and U are six people who form three teams of 2 each . If P is not working with Q or R, Q is not working with R or S, R is not working with Sn or T, then P is working with ?

Cannot be determined

SOLUTION

Solution : A

P can be working with S, T, or U;
Q can be working with T or U and
R can be working with U only.
$∴$ R will be working with U, Q will be working with T and P will be working with S.

Question 21

If the numbers are arranged in the descending order, which number shall be in the third position?

SOLUTION

Solution : A

Since P is a even multiple of 11, the possibilities are 22,44,66,88. Out of which 22, 66 and 88 are not possible because P+J=76 and the maximum difference between first & last number can be 16 (given that the numbers are 8 consecutive 2 digit numbers)
Thus P=44.
L+O=74 and O can only be 30 or 40( reason- max. difference between the first & last number = 14 )
O cannot be 30, as $L \neq 44$ because P is already 44
Thus O=40, L=34, P=44 and J= 32
We can now see that the range of the numbers is between 30 and 44 or 32 and 46
K needs to end with 0, thus K=30 and the range of numbers is 30-44
Q is an even multiple of 7= 42
Also $\frac{N}{2}$ is odd $=>$ N= 38. Thus, M= 36.

option (a) the third number in descending order is O=40

Question 22

What is the median of the numbers?

37.5

36.5

SOLUTION

Solution : D

The median is the average of the middle 2 numbers $= \frac{36 + 38}{2} = 37.$ Option (d)

Question 23

If the selling price per unit of product B is 527 then what is its profit percentage?

43.3

13.3

33.3

23.4

SOLUTION

Solution : D

Total units of product B = $(\frac{18}{100})$ $\times$ 4000 = 720
Total cost = $(\frac{28}{100})$ $\times$ 11 = 3.08lakhs
Cost per unit = $(\frac{3.08}{720})$ = 427
As the selling price is 527 the profit percentage = 23.4%

Question 24

For how many of the five products is the cost per unit more than the average cost of all the given products?

SOLUTION

Solution : A

Cost per unit of A = $\frac{(\frac{19}{100}) \times 11}{(\frac{24}{100}) \times 4000}$ = 217
Cost per unit of C = $\frac{(\frac{18}{100}) \times 11}{(\frac{19}{100}) \times 4000}$ = 148
Cost per unit of D = $\frac{(\frac{20}{100}) \times 11}{(\frac{17}{100}) \times 4000}$ = 229
Cost per unit of E = $\frac{(\frac{20}{100}) \times 11}{(\frac{22}{100}) \times 4000}$ = 229

Average cost of all the given products = $\frac{(217 + 427 + 148 + 229 + 229)}{5}$ = $\frac{1250}{5}$ = 250.
Therefore, only for B, the cost per unit is more than the average cost of all the given products.

Question 25

SOLUTION

Solution : $\begin{matrix} Y e a r & 2002 & 2003 & 2004 & 2005 & 2006 & 2007 * T r a i n e e s & 220 & 270 & 312 & 351 & 365 & 365 E m p l o y e d & 18 & 30 % o f 60 = 18 R e c r u i t e d & 18 / (30 %) = 60 & (312 + 18) - 270 = 60 & (365 + 18) - 351 = 32 * * T r a i n e e s & 0 & 0 & 80 & 190 & 244 & 259 E m p l o y e d & 30 % O f 80 = 24 & 30 % o f 110 = 33 R e c r u i t e d & 80 & 190 - 30 = 110 & (244 + 24) - 190 = 78 & (259 + 33) - 244 = 48 \end{matrix}$

Note: * $\to$ Jacobsons ('00 people)
** $\to$ Robinsons ('00 people)
Ans: 4600

The difference between the no of recruitments by Jacobsons and Robinsons in 2006 = 7800 - 3200 = 4600

Question 26

If Jacobsons recruited 7000 freshers as trainees in 2003, what is the difference in no of trainees being actually absorbed as employees at the two firms in 2007?
___

SOLUTION

Solution : Ans: 1500
If Jacobsons recruited 7000 trainees in 2003, then:
Confirmed as employees in 2005 = 2100
More recruited in 2005= 6000
Confirmed as employees in 2007= 1800
Robinsons confirmed 3300 trainees as employees in 2007, thus the difference= 3300 -1800=1500.

Question 27

How many trainees at Robinsons were absorbed as employees by end of 2007?
___

SOLUTION

Solution :
No of trainees confirmed by Robinsons by 2007 end = 2400+3300=5700.

Question 28

From 2008 onwards the no of recruitment of trainees increases by 10% at Jacobsons and 20% at Robinsons. In which year would the no of these new trainees cross 10,000?___

SOLUTION

Solution : Ans: 2011
The number of fresh recruits would grow as:
$\begin{matrix} Y e a r & 2007 & 2008 & 2009 & 2010 & 2011 J a c o b s o n s (^{'} 00) & 365 & 401.5 & 441.65 & 485.82 & 534.4 R i c h a r d s o n s (^{'} 00) & 259 & 310.8 & 372.96 & 447.55 & 537.06 T o t a l & 624 & 712.3 & 814.61 & 933.37 & 1071.46 \end{matrix}$

Question 29

What could be the size of the team that includes G?

More than one of the above

SOLUTION

Solution : D

The conditions with respect to G are:
$ð$ If G is included, F also must be included
$ð$ If G is included, C and I cannot be included
Thus, some of the possible teams that can be formed are:
a) AEJGDF b) ADGFE c) EGFH
More arrangements are also possible. Hence, it is not possible to determine the size of the team uniquely.

Question 30

What would be the size of the largest possible team?

SOLUTION

Solution : C

The largest possible team can have 6 members. As one of (E, B), (D, H) and two of (C, G, I) must definitely be excluded. Therefore, a minimum of 4 members must be excluded to form any team.

Question 31

Who cannot be included in a team of 6?

SOLUTION

Solution : B

If a 6 member team is to be formed including H, neither A nor D can be included in that team and further one of (E, B) and two of (C, G, I) must be excluded making the size of the team as 5. Therefore, answer option (b) is the correct answer choice.

Question 32

What can be the size of the team that includes C?

More than one of the above

SOLUTION

Solution : B

If C is included, G, I and F must be excluded.
As F is excluded, J also must be excluded.
As F and I are excluded, the only remaining defender D must be included.
As D is included, A must be included and thus H must be excluded.
As G and H are excluded, the only remaining midfielder B must be included.
As B is included, E must be excluded.
Therefore, the team that gets formed is (A, B, C, D).
