Q 1 - Find the angle between the hour hand and minute hand of a clock when time is 5.20 a.m?
Answer : B
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?
Answer : D
Explanation
3 + $\frac{45}{6}$ = (3 + $\frac{3}{4}$)×30 = 112$\frac{1}{2}^{\circ}$
Q 3 - A clock strikes 5 taking 8 sec. In order to strike 9 at the same rate the time taken is
Answer : C
Explanation
Time taken for first interval = 2 sec
Time taken for 8 intervals = 2 × 8 = 16
Q 4 - At what time between 8 and 9 O`clock in the morning, will the hands of a clock be at right angle?
A - $\frac{574}{11}$ min past 8, $\frac{384}{11}$ min past 8
B - $\frac{575}{11}$ min past 8, $\frac{377}{11}$ min past 8
C - $\frac{576}{11}$ min past 8, $\frac{376}{11}$ min past 8
D - $\frac{577}{11}$ min past 8, $\frac{374}{11}$ min past 8
Answer : A
Explanation
(5n±8) × $\frac{12}{11}$; n = 8
$\frac{574}{11}$ min. past 8, $\frac{384}{11}$ min past 8
Q 5 - A watch which gains uniformly is 2 minutes slow at noon on Monday and 4 min 48 sec fast at 2.40 pm on the following day. At what time it was correct?
Answer : B
Explanation
From 12 noon to 2 pm on the following day
There are 7 day and 2 hours = 170 hours
Now watch gains 2 + 4$\frac{4}{5}$ = $\frac{34}{5}$ min in 170 hrs
It will gain 2 min $\frac{170 \times 5}{34}$ × 12 = 50 hrs = 2 days 2 hrs.
Q 6 - At what time between 10 and 11 O`clock the two hands of a clock be coincide together?
A - 53$\frac{6}{11}$ min past 10
B - 54$\frac{6}{11}$ min past 10
Answer : B
Explanation
$\frac{60n}{11}$ = $\frac{60 \times 10}{11}$ = 54$\frac{6}{11}$
Q 7 - How many times the hands of a clock points towards each other in 24 hours?
Answer : C
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 the two hands of a clock look like together from 7 O `clock to 8 O` clocks?
Answer : C
Explanation
$\frac{60n}{11} = \frac{60 \times 7}{11} = \frac{420}{11}$ = 8min.$\frac{2}{11}$sec.
Q 9 - What time between 3 and 4 O` clock will the hands of a clock be together?
Answer : B
Explanation
We know that that minute hand gains 15 minute in 60 minute rotation, therefore, 15 minute can be gained in 15 minutes past 3
Q 10 - At what time between 7 O`clock and 8 O`clock will the hands of a clock be in same straight line but not together?
A - 6$\frac{5}{11}$ min past 7
B - 5$\frac{5}{11}$ min past 7
Answer : B
Explanation
$\frac{\left ( 5n - 30 \right ) \times 12}{11}$ min past n(n>6) here n = 7 so, 5$\frac{5}{11}$ min past 7 is correct.
