How many calls did Victor make on Friday?

A. 23
B. 24
C. 25
D. 26

#### SOLUTION

Solution : C

As each student made a total of 150 calls

x + y = 150-(27+18+26+29)

x + y = 50.

From Victor’s statement calls made by Victor on Friday= (x+y)2 =25

Calls made by Robert on Saturday = 150– 24-x-1-y-30-28 = 17

Calls made by Reynolds on Tuesday = 150-(23+30+27+y+6+x-5)=19

Calls made by Sam on Monday = 150 – (23+x+y+4+27 +24)=22

How many calls did Reynolds make on Tuesday?

A. 17
B. 18
C. 19
D. 20

#### SOLUTION

Solution : C

As each student made a total of 150 calls

x + y = 150-(27+18+26+29)

x + y = 50.

From Victor’s statement calls made by Victor on Friday= (x+y)2 =25

Calls made by Robert on Saturday = 150– 24-x-1-y-30-28 = 17

Calls made by Reynolds on Tuesday = 150-(23+30+27+y+6+x-5)=19

Calls made by Sam on Monday = 150 – (23+x+y+4+27 +24)=22

If number of calls made by Sam on Monday is 4 less than number of calls made by him on Wednesday, then what is the number of calls made by Amanda on Saturday?

A. 21
B. 22
C. 23
D. 24

#### SOLUTION

Solution : D

From the question x-4 = 22 x =26

Thus y=24.

Which of the following is definitely false?

A. Sam made more number of calls on Thursday than on Wednesday.
B. Reynolds made more number of calls than Amanda on Saturday.
C. Reynolds made 30 calls on exactly 2 days.
D. Robert made less number of calls on Wednesday than on Tuesday.

#### SOLUTION

Solution : D

Since Reynolds made y+6 calls on Friday and the maximum number of calls a student can make is 30

So y + 6 30

Thus y 24

Thus x 26

From this we interpret statement (d) is definitely false.

Which of the following can be the difference between number of calls made by Reynolds on Friday and Saturday?

A. 1
B. 2
C. 3
D. 4

#### SOLUTION

Solution : D

The difference between number of calls made by Reynolds on Friday and Saturday = | (x-5)-(y+6) |

= |x-y-11|=|39-2y|

Because x=50-y

Now Robert made x+1 calls on Wednesday.

Therefore, x+1 30 x29

y 21

Thus 21y24 gives |39-2y|=3, 5, 7 or 9
