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 - An accurate clock shows 8 Oclock in the morning. Through how many degrees will the hour hand rotate when the clock shows 2 Oclock in the afternoon?

A - 144o

B - 150o

C - 168o

D - 180o

### Explanation

Angle traced by hour hand in 6 hours = $\frac{360}{12}$ × 6 = 180o

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 - A clock shows 9 Oclock in the morning through how many degrees will the hour hand rotate when the clock shows 3 Oclock in the afternoon?

A - 120o

B - 60o

C - 180o

D - 360o

### Explanation

It’s a straight line path so its 180o

Q 5 - If two hands are at 15o, they are 15 min space apart. It happens how many times in every 1 hour?

A - Once

B - Twice

C - Thrice

D - None of these

### Explanation

Q 6 - If a clock strikes at 7 Oclock taking 9 sec in order to strike 10 at the same rate what should be the time taken?

A - 81 sec

B - 16 sec

C - 80 sec

D - 14 sec

### Explanation

Time taken for 1 interval = 9 sec

Time taken for 9 intervals = 9 × 9 = 81 sec.

Q 7 - At what time between 7 and 8 Oclock 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

### Explanation

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 - What should be the angle of the hands of a clock which are inclined at 40 min past 5?

A - 64

B - 66

C - 68

D - 70

### Explanation

40 min past 5 = 60 + $\frac{40}{5}$ = 68

### Explanation

(5n ± x) × $\frac{12}{11}$ min past 11

(5 × 11 ± 6) × $\frac{12}{11}$ = 66$\frac{5}{11}$ min past 11 and 53$\frac{5}{11}$ min past 11

Q 10 - Find the angle between the hour hand and minute hand of a clock when the time is 4.10.

A - 65o

B - 35o

C - 125o

D - 60o

30(n – $\frac{x}{2}$) + $\frac{x}{2}$; n = 4 and x = 10 so, option (a) is correct.
