Question
A invested Rs. X in a scheme. After 6 months, B joined
with Rs 4000 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+4000)×6)/(X × 12 + (X+4000) × 6) 7X + 28000 = 9X + 12000 2X = 16000 X = 8000
