Question

If a clock strikes $12$ in $33$ seconds, it will strike $6$ in how many seconds?

• A. $\frac{33}{2}$
• B. $15$
• C. $12$
• D. $22$

Answer 1

Answer: (B)

$15$

In order to strike 12 there are 11 intervals of equal time = $\frac{33}{11}$ = 3 seconds each
Therefore to strike 6 it has 5 equal intervals, it requires 5 $\times$ 3 =15 sec.
