Q 1 - At what angle the hands of a clock are inclined at 15 minute past 5?

A - 72$\frac{1}{2}^{\circ}$

B - 67$\frac{1}{2}^{\circ}$

C - 58$\frac{1}{2}^{\circ}$

D - 64o

Explanation

Angle 15 minute past 5 = 60 + 7$\frac{1}{2}$ = 67$\frac{1}{2}^{\circ}$

Q 2 - In between 11 and 12 O clock, how many times the two hands will coincide with each other?

A - 60 min.

B - 45 min.

C - 50 min.

D - 55 min.

Explanation

60 min = 12 hours at which the hands will coincide with each other.

Q 3 - The angle between hands of a clock while time is 20 minute past 2 is.

A - 35o

B - 60o

C - 75o

D - 50o

Explanation

the angle through which the hour hand has turned though = (20 × $\frac{1}{2}$) = 10o

Therefore required angle = 60o - 10o = 50o

Q 4 - If a clock is started at noon then what is the angle turned by hour hand at 3.45 pm?

A - 67.5o

B - 97.5o

C - 112.5o

D - 142.5o

Explanation

1 min = $\frac{180}{360}$

225 min = $\frac{180}{360}$ × 225 = 112.5o

Q 5 - In 12 hrs, how many times both hands in opposite direction can be observed?

A - 10 times

B - 11 times

C - 12 times

D - none of these

Explanation

Since in each interval, hands come opposite to each other once at a time. In 12 hours, there are 11 intervals, hence hands will be 11 times opposite in direction.

Q 6 - At what time between 10 and 11 Oclock 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

C - 55$\frac{6}{11}$ min past 10

D - 57$\frac{6}{11}$ min past 10

Explanation

$\frac{60n}{11}$ = $\frac{60 \times 10}{11}$ = 54$\frac{6}{11}$

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

C - 35$\frac{8}{11}$ minute past 3

D - 32$\frac{5}{11}$ minute past 3

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 - What should be the angle of the hands of a clock which are inclined at 40 min past 5?

A - 64

B - 66

C - 68

D - 70

Explanation

40 min past 5 = 60 + $\frac{40}{5}$ = 68

Q 9 - How many times the two hands are 15 minute space apart in 12 hrs?

A - 22 times

B - 24 times

C - 26 times

D - none of these

Explanation

The hands are at right angle two times per hours. so, in 12 hrs = 12 × 2 = 24 times

Q 10 - Find the angle between the hour hand and minute hand of a clock when the time is 4.10.

A - 65o

B - 35o

C - 125o

D - 60o

Explanation

30(n – $\frac{x}{2}$) + $\frac{x}{2}$; n = 4 and x = 10 so, option (a) is correct.
