Question

Rs. 3000 were divided among 100 children. If each girl gets Rs. 50 and each boy gets Rs. 25, then the number of boys is

• A. 20
• B. 40
• C. 60
• D. 80

Answer 1

The correct option is D 80

Let number of girls be x and number of boys be y.

According to the question,

$x+y=100$ .......(1)

$50x+25y=3000$ ........(2)

From equation 1, $x=100-y$

Therefore, in equation 2,

$50(100-y)+25y=3000$

$2(100-y)+y=120$

$y=80$

$x=20$

Therefore, number of boys is 80.
