Proportion of share = 3:7
Let the profits of A and B be Rs 3x and Rs 7x respectively.
3x + 7x = 24500
∴ 10x = 24500
∴ x = 24500/10 = 2450
∴ Profit earned by A = 3x = 3 × 2450 = Rs 7350
Amount given by A = 2% of his profit
= 2/100 × 7350 = Rs 147
Profit earned by B = 7x = 7 × 2450 = Rs 17150
Amount given by B = 2% of his profit
= 2/100 × 17150
= Rs 343
∴ The amount given by A and B to the Soldiers’ Welfare Fund are Rs 147 and Rs 343 respectively.
