Question

In an examination, $65\%$ of the total examinees passed. If the number of failures is $420,$ the total number of examinees is

(a) $500$

(b) $1000$

(c) $1200$

(d) $1625$

Answer 1

The correct option is (c): $1200$

Passed $\%=65$

Failed $\%=100-65=35\%$

Now $35\%$ of total examinees $=420$

$\therefore$ Total examinees $=\frac{420\times 100}{35}=1200$
