Solution
A’s age = 6 years 8 months
= 6 x 12 + 8 = 72 + 8 = 80 months
B’s age = 7 years 4 months = 7 x 12 + 4 = 84 + 4 = 88 months
∴ Ratio between them = 80 : 88 = 10 : 11
Amount = Rs. 3150
Sum of ratios = 10 + 11 =21
∴ A's share = `(3150 xx 10)/21 = 1500` = Rs. 1500
B's share = `(3150 xx 11)/21 = 1650` = Rs. 1650
