Step-by-step explanation:
A sum of Rs.312 was divided among a group of 100 students in such a way that each boy got Rs. 3.60 and each girl got Rs. 2.40
Calculation:
Let the number of boys and girls be x and y respectively
⇒ x + y = 100 --(1)
3.60x + 2.40y = 312 --(2)
Multiply (1) by 3.60
⇒ 3.60x + 3.60y = 360 --(3)
On solving (2) and (3),
⇒ 1.20y = 48
∴ y = 48/1.20 = 40
Number of girls = 40
