Question
A invested Rs X in a scheme. After 6 months, B joined
with Rs 7500 more than that of A. After an year, ratio of profit of B to the total profit was 3: 7. Find the value of X.Solution
Profit of B/Total Profit = 3/7 = ((X + 7500)×6)/(X × 12 + (X + 7500) × 6) 9X + 22500 = 7X + 52500 2X = 30000 X = 15000
