Q 1 - A watch which gains uniformly is 5 min slow at 7 Oclock in the morning on Sunday and it is 5min 48 sec fast at 7 p.m on the following Sunday. Which day was it correct?

A - Friday

B - Saturday

C - Tuesday

D - Wednesday

### Explanation

$\frac{54}{5}$ in 180 hrs

5 min = 180 × $\frac{5}{54}$ = 83 hrs 20 min = 3 days 11 hrs and 20 min.

Its answer is correct at 20 min. past 6 pm on Wednesday.

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$\frac{1}{2}^{\circ}$

### 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 - A clock strikes 5 taking 8 sec. In order to strike 9 at the same rate the time taken is

A - 14 sec

B - 15 sec

C - 16 sec

D - 17 sec

### Explanation

Time taken for first interval = 2 sec

Time taken for 8 intervals = 2 × 8 = 16

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 - $\frac{301}{11}$

### Explanation

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

Q 5 - If a clock is started at noon then angle turned by hour hand at 4.45 pm is?

A - 142$\frac{2}{4}$

B - 142$\frac{3}{4}$

C - 142$\frac{5}{4}$

D - 142$\frac{6}{4}$

### Explanation

(4 + $\frac{45}{60}$) × 30 = 142$\frac{2}{4}$

Q 6 - At what time between 4 and 3 Oclock will the hands of a clock point in opposite direction?

A - $\frac{549}{11}$ min past 4

B - 601 min past 4

C - $\frac{600}{11}$ min past 4

D - 602 min past 4

### Explanation

(5n + 30 )×$\frac{12}{11}$, n = 4

$\frac{50 \times 12}{11}$ min. past 4 = $\frac{600}{11}$

Q 7 - At what time after 6 O clock, the two hands are at right angle for first time?

A - 49$\frac{1}{11}$ min past 6

B - 48$\frac{1}{11}$ min past 6

C - 47$\frac{1}{11}$ min past 6

D - 46$\frac{1}{11}$ min past 6

### Explanation

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

$\frac{540}{11}$ = 49$\frac{1}{11}$ min past 6

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

Q 9 - Calculate the time from 10.15 a.m to 11.30 p.m on Wednesday?

A - 13 hrs 30 min

B - 13 hrs 25 min

C - 13 hrs 20 min

D - 13 hrs 15 min

### Explanation

Total hour = 11.30 – 10.15 = 1.15

12.00 + 1.15 = 13 hrs 15 min.

(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
