Image result for clinical thermometer

Question 3

This clock is 15 minutes fast. What is the correct time?

A.

10:50

B.

10:55

C.

10:15

D.

10:20

SOLUTION

Solution : A

Time an clock = 11:05

Clock is 15 minutes fast

Hence, go 15 minutes backwards to get the right time 

[1 hours = 60 minutes 60 + 5 = 65 minutes]

 

Question 4

8 minutes + 6 minutes - 2 minutes = ______ seconds 

A.

270 seconds 

B.

800 seconds

C.

740 seconds

D.

720 seconds

SOLUTION

Solution : D

8 + 6 - 2 = 14 - 2 = 12 minutes

1 minute = 60 seconds

∴ 12 minutes = 12 × 60 = 720 seconds 

Answer = 720 seconds

Question 5

Water freezes at ____.

A.

100∘C

B.

0∘C

C.

37∘C

D.

20∘C

SOLUTION

Solution : B

Freezing point of water = 0∘C. At this temperature, water turns to ice.

Question 6

6 hours after 9:45 AM is:

A.

3:45 PM

B.

12:45 AM

C.

Noon

D.

1:00 PM

SOLUTION

Solution : A

6 hours after 9:45 AM is

   9:45+6:00–––––––– 15:45––––––––

15:45 when converted to 12-hour time format is 3:45 PM.

Question 7

3 hours 10 minutes - 2 hours 55 minutes = ______ seconds

 

A.

900 seconds

B.

1200 seconds

C.

600 seconds 

D.

450 seconds

SOLUTION

Solution : A


1 minute = 60 seconds

∴ 15 minutes = 60 × 15 = 900 seconds

Question 8

A train leaves Bengaluru at 22:35 hours and reaches Chennai after 6 hours 10 minutes. At what time did the train reach Chennai?

A.

4:35 AM

B.

5:35 AM

C.

4:45 AM

D.

5:00 AM

SOLUTION

Solution : C

Time train leaves Bangalore = 22:35 hours or 10:35 PM

Time of travel = 6 hours 10 minutes 

10:35 PM to 4:35 AM is 6 hours

35 + 10 = 45 

Hence, the train reaches at 4:45 AM

Question 9

In a chemistry lab, 2 reactions are taking place each in 2 beakers. One at 149∘ F (R1) and another at 70∘ C (R2). Which reaction occurs at a higher temperature?

A.

R1

B.

R2

C.

both occur at same temperature

D.

cannot say

SOLUTION

Solution : B

R1 ∘C = (∘F−32)×59

∘F = 149

∘C = (149−32)×59=117×59

∘C = 13 × 5 = 65∘ C

R1 proceeds at 65∘ C

R2 proceeds at 70∘ C

Answer : R2 at 70∘ C is at a higher temperature

Question 10

The time duration from 23:40 to 01:10 is ____ minutes less than the time duration from 14:35 to 17:05.

A.

40 minutes

B.

30 minutes

C.

60 minutes

D.

35 minutes

SOLUTION

Solution : C

a) 23:40 to midnight (00:00) = 20 minutes

midnight (00:00) to 1:10 = 1 hour 10 minutes

∴ 23:40 to 1:10 = 1 hour 10 minutes + 20 minutes = 1 hour 30 minutes


b) 14:35 to 17:05

is 2 hours 30 minutes

Difference in the time

   H   Mins    2:30− 1:30–––––––––    1:00–––––––––

1 hour = 60 minutes
