Given: X’s investment in first 6 months = 19000 Y’s investment in first 6 months = 22000 X’s investment in last 6 months = 30000 Y’s investment in last 6 months = 33000 Total profit = 52000 Concept: Ratio in which they should share the profit = ratio of (investment × time period) Calculation: Ratio in which X and Y should share profit = (19000 × 6 + 30000 × 6) : (22000 × 6 + 33000 × 6) ⇒ X : Y = (49000 × 6) : (55000 × 6) ⇒ X : Y = 49 : 55 Difference between the shares of Y and X = 52000 ×
