Q 1 - How many times do the hands of a clock point towards each other in a day?
Answer : D
Explanation
In 12 hours the hands of a clock point towards each other 11 times then in a day they will point towards each other 22 times.
Q 2 - An accurate clock shows 8 O`clock in the morning. Through how many degrees will the hour hand rotate when the clock shows 2 O`clock in the afternoon?
Answer : D
Explanation
Angle traced by hour hand in 6 hours = $\frac{360}{12}$ × 6 = 180o
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 - 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 - How many times in one hour both the hands will coincide each other in between 3 and 4 O`clock?
Answer : A
Explanation
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 `n’; 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 - At what time after 6 O` clock, the two hands are at right angle for first time?
A - 49$\frac{1}{11}$ min past 6
B - 48$\frac{1}{11}$ min past 6
Answer : A
Explanation
( 5n + 15) × $\frac{12}{11}$ here , n= 6
$\frac{540}{11}$ = 49$\frac{1}{11}$ min past 6
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 - The minute hand of a clock overtakes the hour hand at an interval of 70 min of the correct time. How much time in a day does the clock gain or loss?
A - $\frac{7200}{77}$ min gain
B - $\frac{7300}{77}$ min loss
Answer : C
Explanation
$\left ( \frac{720}{11} - x \right ) \times\left ( \frac{60 \times 24}{x} \right )$ min
$\left ( \frac{720}{11} - 70 \right ) \times\left ( \frac{60 \times 24}{70} \right )$ min = -$\frac{7200}{77}$ min(loss)
Q 10 - At what time between 3 O`clock and 4 O`clock will the hands of a clock be in opposite direction?
A - 49$\frac{1}{11}$ min past 3
B - 50$\frac{1}{11}$ min past 3
Answer : A
Explanation
$\frac{\left ( 5n + 30 \right ) \times 12}{11}$ (n>6) min past n
So 49$\frac{1}{11}$ min past 3 is correct.
