A
5 min. past 7

B
5211 min. past 7

C
5311 min. past 7

D
5511 min. past 7

Solution

The correct option is D $$5\displaystyle\frac{5}{11}$$ min. past $$7$$
When the hands of the clock are in the same straight line but not together, they are $$30$$ minute spaces apart. At $$7$$ o'clock, they are $$25$$ min. spaces apart.
$$\therefore$$  Minute hand will have to gain only $$5$$ min. spaces.
$$55$$ min. spaces are gained in $$60$$ min.
$$5$$ min. spaces are gained in $$\left( \displaystyle\frac { 60 }{ 55 } \times 5 \right)$$ min. $$=5\displaystyle\frac{5}{11}$$ min.
$$\therefore$$  Required time $$=5\displaystyle\frac{5}{11}$$ min. past $$7$$
