16:15

C.

12:15 PM

D.

14:15

#### SOLUTION

Solution : B

4 hours 15 minutes after midday (12 noon) is:

What is the instrument used to measure body temperature?

A.

Barometer

B.

Thermometer

C.

Clinical thermometer

D.

Thermograph

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]

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

Water freezes at ____.

A.

100C

B.

0C

C.

37C

D.

20C

#### SOLUTION

Solution : B

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

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.

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

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

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 = (F32)×59

F = 149

C = (14932)×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

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
