Questions and Answers

Q 1 - How much time does a watch gain per day, if its hands coincides in every 64 min.?

A - 37 min.

B - $32\frac{8}{11}$ min

C - 31 min.

D - None of these

Answer : B

Explanation

$\left ( \frac{720}{11} - x\right )\times\left ( \frac{60\times24}{x} \right )$ min.

Put x = 64, then $32\frac{8}{11}$ min. is correct.

Q 2 - The reflex angle between the hands of a clock at 10:25 is?

A - 180o

B - 192$\frac{1}{2}^{\circ}$

C - 195o

D - 197$\frac{1}{2}^{\circ}$

Answer : D

Explanation

By hour hand $\frac{360}{12} \times \frac{125}{12} = 312 \frac{1}{2}^{\circ}$

By min hand $\frac{360}{12} \times 25^{\circ}$ = 150o

Reflex angle = 360o - (312$\frac{1}{2}^{\circ}$ - 150o) = 360o - 162$\frac{1}{2}^{\circ}$ = 197$\frac{1}{2}^{\circ}$

Q 3 - On reaching the place of meeting 20 min. before 8.50 am Sumit found himself 30 min earlier than the man who was 40 min late. What was scheduled time of the meeting?

A - 8.00 am

B - 8.05 am

C - 8.10 am

D - 8.20 am

Answer : D

Explanation

Sumit reached the place at 8.30 am and the man who was late by 40 min reached the place at 9 am, so the meeting was 40 min before i.e 8.20 am.

Q 4 - In which particular time between 5 and 6 O` clock will the hands of clock be together?

A - $\frac{298}{11}$

B - $\frac{299}{11}$

C - $\frac{300}{11}$

D - $\frac{301}{11}$

Answer : C

Explanation

$\frac{60n}{11}$ = $\frac{60 \times 5}{11}$ = $\frac{300}{11}$

Q 5 - What is the value of angle covered by minute the hand in one minute?

A - 5o

B - 6o

C - 7o

D - 8o

Answer : B

Explanation

$\frac{360}{60}$ = 6o

Minute Hand Angle

Q 6 - A clock shows 12 O`clock in the mid night. Through how many degrees will the hour hand rotate when the clock shows 6 am in the morning?

A - 60o

B - 120o

C - 180o

D - 240o

Answer : C

Explanation

It is a straight line path so its 180o

Q 7 - At what time between 7 and 8 O`clock will the hands of a clock be in opposite direction?

A - 20$\frac{10}{11}$ minute past 7

B - 30$\frac{10}{11}$ minute past 7

C - 10$\frac{10}{11}$ minute past 7

D - 15$\frac{10}{11}$ minute past 7

Answer : C

Explanation

Clock Hands Opposite Direction

From the figure it is clear that the minute hand has to gain 10 minute space in order to be in opposite of hour hand, therefore 10 minute space can be gained in $\frac{60}{55}$ × 10 = 10$\frac{10}{11}$

Q 8 - At what time from 10 O `clock to 11 O` clock the hands coincide each other?

A - 57$\frac{3}{11}$

B - 57$\frac{4}{11}$

C - 57$\frac{5}{11}$

D - 57$\frac{6}{11}$

Answer : D

Explanation

Hands Coincide Each Other

$\frac{60}{55}$ × 53 = 57$\frac{6}{11}$

Q 9 - Calculate the angle between the hour hand and minute hand of a clock at 5.40.

A - 40o

B - 50o

C - 60o

D - 70o

Answer : D

Explanation

Required angle = 240 – 170 = 70o

Answer : A

Explanation

(5n ± x) × $\frac{12}{11}$ past n = (5 × 3 ± 4) × $\frac{12}{11}$ = 20 $\frac{8}{11}$ min past 3 and 12 min past 3
