A sum of money is divided among 160 males and some females in the ratio 16 : 21. Individually each male gets ₹ 4 and a female ₹ 3 . The number of females is
(a)198
(b)270
(c)280
(d)284
Answer
Answer (as printed): C
Explanation
Let the number of females be $x$. Then, $\frac{160 \times 4}{3 x}=\frac{16}{21} \Rightarrow 48 x=160 \times 4 \times 21$ $\Rightarrow x=\frac{160 \times 4 \times 21}{48}=280$.
