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

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 - In between 11 and 12 O clock, how many times the two hands will coincide with each other?

A - 60 min.

B - 45 min.

C - 50 min.

D - 55 min.

Explanation

60 min = 12 hours at which the hands will coincide with each other.

Q 3 - At what time between 8 and 9 Oclock will the hands of a clock be in straight line?

A - 11$\frac{11}{11}$ min past 8

B - 11$\frac{10}{11}$ min past 8

C - 11$\frac{9}{11}$ min past 8

D - 11$\frac{8}{11}$ min past 8

Explanation

$\left ( \frac{5n - 30}{11} \right )$ × 12 min past (n>6)

$\frac{120}{11}$ = 11 $\frac{10}{11}$ past 8

Q 4 - At what time after 5 Oclock hour hand and the minute hand are at right angle for the first time?

A - 5 hrs 43$\frac{7}{11}$ min

B - 5 hrs 40$\frac{7}{11}$ min

C - 5 hrs 42$\frac{7}{11}$ min

D - 5 hrs 41$\frac{7}{11}$ min

Explanation

(5n + 15) × $\frac{12}{11}$; n = 5

$\frac{480}{11}$ = 43$\frac{7}{11}$

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 - 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 - How many hours and minutes a watch gains per day, if its hands coincide in every 60 minutes?

A - 130 hrs $\frac{10}{11}$ min

B - 130 hrs $\frac{8}{11}$ min

C - 130 hrs $\frac{9}{11}$ min

D - none of these

Explanation

$\left ( \frac{720}{11} - x \right ) \times \left ( \frac{60 \times 24}{x} \right )$ min

Here x = 60; $\left ( \frac{720 - 660}{11} \right ) \times\left ( \frac{60 \times 24}{60} \right )$ = 130 hrs$\frac{9}{11}$ min.

Q 10 - The minute hand of a clock overtakes the hour hand at an interval of 63 min of the correct time. How much time does a clock gain or loss in a day?

A - 55$\frac{8}{17}$ min

B - 56$\frac{8}{17}$ min

C - 56$\frac{7}{17}$ min

D - 58$\frac{7}{17}$ min

($\frac{720}{11}$ - x) × ($\frac{60 \times 24}{x}$) min; here x = 63 so, option (b) is correct
