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
