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 - In between 11 and 12 O` clock, how many times the two hands will coincide with each other?
Answer : A
Explanation
60 min = 12 hours at which the hands will coincide with each other.
Q 3 - Four bells ring at interval of 30 min, 1 hrs, 1$\frac{1}{2}$hrs, 1 hrs and 45 min respectively. All the bell rings simultaneously at 12 noon they will again ring simultaneously at.
Answer : D
Explanation
L.C.M of 30, 60, 90 and 105 =1260 hence all the bells ring after 1260 min i.e at 9 am
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 - If two hands are at 15o, they are 15 min space apart. It happens how many times in every 1 hour?
Answer : C
Explanation
Q 6 - A clock shows 12 O`clock in the mid night. Through how many degrees will the hour hand rotate when the clock shows 6 am in the morning?
Answer : C
Explanation
It is a straight line path so its 180o
Q 7 - At what time between 3.30 and 4 O`clock will the hands of a clock be at right angle?
A - 32$\frac{8}{11}$ minute past 3
B - 45$\frac{8}{11}$ minute past 3
Answer : A
Explanation
It is clear from the figure that minute hand has to travel through 30 minute space.
Therefore 30 minute space can be gained in $\frac{12}{11}$ × 30 = 32 $\frac{8}{11}$ minute past 3
Q 8 - If a clock started at noon then what should be the angle at 7.25 pm?
Answer : B
Explanation
(7 + $\frac{25}{12}$) × 30 = $\frac{445}{2}$ = 222$\frac{5}{2}$
Q 9 - How many times the two hands are 15 minute space apart in 12 hrs?
Answer : B
Explanation
The hands are at right angle two times per hours. so, in 12 hrs = 12 × 2 = 24 times
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?
Answer : B
Explanation
($\frac{720}{11}$ - x) × ($\frac{60 \times 24}{x}$) min; here x = 63 so, option (b) is correct
