Q 1 - How much time does a watch gain per day, if its hands coincides in every 64 min.?
Answer : B
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 - A clock is started at noon. By 10 minute past 5, the hour hand has turned through?
Answer : C
Explanation
12 hours = 360o
5 hrs.10 min = $\frac{31}{6}$ hrs = 155o
Q 3 - Ayush leaves his house at 20 min. to 7 in the morning reaches Tushar`s house in 25 min. They finish their breakfast in another 15 mins and leave for office which takes another 35 min. at what time they leave Tushar`s house to their office?
Answer : C
Explanation
Ayush leaves his house at 6.40 am. He reaches Tushar`s house in 25 min. i.e at 7.05 am and 15 min. after it means 7.20 am.
Q 4 - Number of hours and minutes from 6.20 am to 9.30 pm on the same day is
Answer : A
Explanation
total 9.30 – 6.20 = 3.10
12.00 + 3.10 = 15 hours 10 minutes
Q 5 - What should be the angle between hour hand and minute hand of a clock when the time is 6.45?
Answer : B
Explanation
$\frac{360}{12}$ × $\frac{27}{4}$ = 202.5o and $\frac{360}{60}$ × 45 = 270o
Required angle 270 - 202.5 = 67.5o
Q 6 - In which particular time between 4 and 5 O`clock will the hands of a clock coincide together?
Answer : B
Explanation
There are 20 min space apart so, $\frac{60}{55}$ × 20 = 21 $\frac{9}{11}$
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 - Calculate the reflex angle at 9. 45 a.m.
Answer : C
Explanation
$\frac{360}{12} \times \frac{117}{12} = 292\frac{5}{12}$
$\frac{360}{60}$ × 45 = 270
Reflex angle = 360- (292$\frac{5}{12}$ - 270) = 337$\frac{5}{12}$
Q 9 - At which point of time after 5 O` clock, both hands are at right angle to each other for the first time?
Answer : B
Explanation
(5n + 15) × $\frac{12}{11}$; here n = 5
$= 40 \times \frac{12}{11} = 43\frac{6}{11}$ min past 5
Q 10 - At what time between 7 O`clock and 8 O`clock in the morning will the hands of a clock be at right angle?
A - $\frac{500}{11}$ min past 7 and $\frac{340}{11}$ min past 7
B - $\frac{440}{11}$ min past 7 and $\frac{280}{11}$ min past 7
C - $\frac{600}{11}$ min past 7 and $\frac{240}{11}$ min past 7
D - $\frac{340}{11}$ min past 7 and $\frac{120}{11}$ min past 7
Answer : C
Explanation
(5n ± 15) × $\frac{12}{11}$; here n = 7
Then, $\frac{600}{11}$ min past 7 and $\frac{240}{11}$ min past 7
