Q 1 - Find the angle between the hour hand and minute hand of a clock when time is 5.20 a.m?

A - 45o

B - 40o

C - 50o

D - 35o

### Explanation

$30\left ( n-\frac{x}{5} \right )+\frac{x}{5}$

$= 30(5 - 4) + 10 = 40^{\circ}$

Q 2 - If a clock started at noon, then the angle turned by hour hand at 3.45 pm is?

A - 104$\frac{1}{2}^{\circ}$

B - 117$\frac{1}{2}^{\circ}$

C - 97$\frac{1}{2}^{\circ}$

D - 112$\frac{1}{2}^{\circ}$

### Explanation

3 + $\frac{45}{6}$ = (3 + $\frac{3}{4}$)×30 = 112$\frac{1}{2}^{\circ}$

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

### 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 - If a clock is started at noon then what is the angle turned by hour hand at 3.45 pm?

A - 67.5o

B - 97.5o

C - 112.5o

D - 142.5o

### Explanation

1 min = $\frac{180}{360}$

225 min = $\frac{180}{360}$ × 225 = 112.5o

Q 5 - What should be the angle between hour hand and minute hand of a clock when the time is 6.45?

A - 66.5o

B - 67.5o

C - 68.5o

D - 69.5o

### Explanation

$\frac{360}{12}$ × $\frac{27}{4}$ = 202.5o and $\frac{360}{60}$ × 45 = 270o

Required angle 270 - 202.5 = 67.5o

### Explanation

(5n ± 15) × $\frac{12}{11}$ min past 6, here n = 6

Therefore 49$\frac{1}{11}$ min past 6 and 16$\frac{4}{11}$ min past 6

Q 7 - How many times the hands of a clock points towards each other in 24 hours?

A - 20

B - 21

C - 22

D - 23

### Explanation

In general its 11 times points towards each other in 12 hours then in 24 hrs it is double i.e 22 times.

Q 8 - At what time in between 7.30 am to 8.30 am in the morning, the hands are in straight line?

A - $\frac{90}{11}$ min past 7.30

B - $\frac{91}{11}$ min past 7.30

C - $\frac{89}{11}$ min past 7.30

D - $\frac{92}{11}$ min past 7.30

### Explanation $\frac{\left ( 5n - 30 \right ) \times 12}{11}$ (n>6)

$\frac{\left ( 5 \times \left ( \frac{15}{2} \right ) - 30 \right ) \times 12}{11} = \frac{90}{11}$ min past 7.30

Q 9 - At which point of time after 5 O` clock, both hands are at right angle to each other for the first time?

A - 5h, 43$\frac{4}{11}$ min

B - 5h, 43$\frac{6}{11}$ min

C - 5h, 43$\frac{5}{11}$ min

D - 5h, 43$\frac{7}{11}$ min

### Explanation

(5n + 15) × $\frac{12}{11}$; here n = 5

$= 40 \times \frac{12}{11} = 43\frac{6}{11}$ min past 5

Q 10 - What will be angle between two hands of a clock at 9.50? A - 6o

B - 5o

C - 4o

D - 3o
