Questions and Answers

Q 1 - How many times do the hands of a clock point towards each other in a day?

A - 24

B - 20

C - 12

D - 22

Answer : D

Explanation

In 12 hours the hands of a clock point towards each other 11 times then in a day they will point towards each other 22 times.

Q 2 - At 3.40, the hour hand and the minute hand of a clock forms an angle of?

A - 120o

B - 125o

C - 130o

D - 135o

Answer : C

Explanation

$\frac{360}{12} \times \frac{11}{3}$ = 110o and $\frac{360}{60} \times 40$ = 240o

Required angle 240 – 110 = 130o

Q 3 - A clock shows 10 O `clock in the morning. How many degrees will the hour hand rotate when the clock shows 4 O` clock in the afternoon?

A - 144o

B - 150o

C - 168o

D - 180o

Answer : D

Explanation

Angle turned in 6 hrs = $\frac{360}{12}$ × 6 = 180o

Q 4 - Number of hours and minutes from 6.20 am to 9.30 pm on the same day is

A - 15 hours 10 mins

B - 15 hours 20 mins

C - 15 hours 05 minutes

D - 15.00 hours

Answer : A

Explanation

total 9.30 – 6.20 = 3.10

12.00 + 3.10 = 15 hours 10 minutes

Q 5 - In 12 hrs, how many times both hands in opposite direction can be observed?

A - 10 times

B - 11 times

C - 12 times

D - none of these

Answer : B

Explanation

Since in each interval, hands come opposite to each other once at a time. In 12 hours, there are 11 intervals, hence hands will be 11 times opposite in direction.

Q 6 - In which time between 9 and 10 O`clock, the hands of a clock will look like a straight line?

A - $\frac{180}{11}$

B - $\frac{210}{11}$

C - $\frac{90}{11}$

D - $\frac{270}{11}$

Answer : A

Straight Line

Explanation

$\frac{60}{55}$ × 15 = $\frac{180}{11}$

Q 7 - What should be the angle between two hands of a clock at 7.20 a.m?

A - 95o

B - 105o

C - 110o

D - 100o

Answer : D

Explanation

30(7-$\frac{20}{5}$) + $\frac{20}{2}$ = 30 × 3 + 10 = 100o

Q 8 - What is the angle between two hands of a clock when time is 10.20 O`clock?

A - 150o

B - 180o

C - 170o

D - 145o

Answer : C

Explanation

Angle traveled by minute hand in 20 minute = 6 + 20 = 120o

Also angle travelled by hour hand = $\frac{1}{2}$ × 20 = 10o

Therefore required angle = (60 - 10) + 120 = 170o

Answer : B

Explanation

$\frac{360}{12} \times \frac{39}{12} = 97\frac{5}{144}$ and $\frac{360}{60} \times 25 = 150$

Required angle = 150 - 97$\frac{5}{144}$ = 52$\frac{5}{144}$

Q 10 - If a proper-working clock displays 8:00AM, how may degrees will the hour hand rotate when the clock shows 2:00 PM?

A - 144 degrees

B - 150 degrees

C - 168 degrees

D - 180 degrees

Answer : D

Explanation

Angle traced by the hour hand in 6 hours = ($\frac{360}{12}$) × 6 degrees = 180 degrees
