Question

If Rs. $50$ is distributed amount $150$ children giving $50$ p to each boy and $25$ p to each girl. Then the number of boys is

• A. $25$
• B. $40$
• C. $36$
• D. $50$

Answer 1

The correct option is D $50$

Let number of boys $=x$
Number of girls $=y$
Then, $x+y=150$ .....(1)
and $0.5x+0.25y=50$

$\Rightarrow 2x+y=200$ ......(2)
Subtracting (1) from (2), we get
$x=50$
Thus, number of boys are $50$.
