Q:

At what time between 2 and 3 O'clock, the hands of a clock coincide ?

A) 1 10/11 minutes past 2	B) 1 10/11 minutes past 3
C) 1 11/10 minutes past 3	D) 11 10/11 minutes past 2

Answer & Explanation Answer: A) 1 10/11 minutes past 2

Explanation:

Since, in one hour, two hands of a clock coincide only once, so, there will be value.
Required time $T = \frac{2}{11} (H \times 30 + A^{o})$ minutes past H.
Here H - initial position of hour hand = 2 (since 2 O'clock)
A° = Required angle = 0° (Since it coincides)

$T = \frac{2}{11} (2 \times 30 + 0^{o})$ minutes past 2

=> $1 \frac{10}{11}$ minutes past 2
