Answer: No. of girls = 200

Step-by-step explanation:

Total amount = ₹232

Total children= 480

Let no. boys= x

No. of girls= y

Then, x+y = 480 ........ (1)

Also, A/Q,

0.4x + 0.6y= 232

Multiply by 10 both sides,

4x+6y= 2320

Divide by 2 both sides

2x+ 3y= 1160 ............... (2)

Multiply (1) by 2, we get

2x+2y= 960 ........ (3)

Subtract (3) from (2) , we get

2x+ 3y -2x -2y= 1160-960

y= 200

Put y=200 in (1),

x+200= 480

x= 480-200= 280

No. of girls = y = 200
