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 - What is the angle between minute hand and the hour hand of a clock when time is 4.20?
Answer : B
Explanation
Angle traced by hour hand in 13/3 hrs = ( $\frac{360}{12}$ × $\frac{13}{3}$) = 130o
Angle traced by min hand in 20 min = $\frac{360}{12}$ × 20 = 120o
Therefore required angle = 130 - 120 = 10o
Q 4 - At what time after 5 O`clock 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
Answer : A
Explanation
(5n + 15) × $\frac{12}{11}$; n = 5
$\frac{480}{11}$ = 43$\frac{7}{11}$
Q 5 - In a period of 12 hours, how many times the hands are at right angle to each other?
Answer : A
Explanation
The hands are at right angle to each other 2 times in each hour
So, In 12 hour there are 11 intervals, therefore hands will be at right angle 22 times in 12hrs.
Q 6 - At which time the hands of a clock in between 11 and 12 O`clock will 6 min space apart?
A - 65$\frac{6}{11}$ min past 11 and 52$\frac{5}{11}$ min past 11
B - 64$\frac{6}{11}$ min past 11 and 52$\frac{5}{11}$ min past 11
C - 63$\frac{6}{11}$ min past 11 and 50$\frac{5}{11}$ min past 11
D - 66$\frac{6}{11}$ min past 11 and 53$\frac{5}{11}$ min past 11
Answer : D
Explanation
(5n ± x) × $\frac{12}{11}$ min past `nā; here n = 11
(5 × 11 ± 6) × $\frac{12}{11}$ = 66$\frac{6}{11}$ min past 11 and 53$\frac{5}{11}$ min past 11
Q 7 - What is the exact time between 8 and 9 O`clock when hands are coincide together?
A - 41$\frac{7}{11}$ minute past 8
B - 42$\frac{7}{11}$ minute past 8
Answer : C
Explanation
To get together the minute hand has to travel through 40 minute space.
We know that minute hand gains 55 minute in 60 minute, 40 minute can be gained in
40 × $\frac{12}{11}$ = 43$\frac{7}{11}$ minute past 8
Q 8 - Ram takes 15 minutes to reach Madhu`s house, by walking. while he takes only 8 min to reach Madhu`s house by driving a vehicle. What is the difference of separation of time?
Answer : B
Explanation
(15 - 8) = 7 min.
Q 9 - Calculate the angle between the hour hand and minute hand of a clock at 5.40.
Answer : D
Explanation
Required angle = 240 ā 170 = 70o
Q 10 - At what time between 3 O`clock and 4 O` clock will the hands of a clock be 4 min apart?
A - 20$\frac{8}{11}$ min past 3 and 12 min past 3
B - 20$\frac{7}{11}$ min past 3 and 11 min past 3
Answer : A
Explanation
(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
