P start a business with Rs. 10000, Q joins him after 2 month with 20% more investment than P, after 2 month R joins him with 40% less than Q. If the profit earned by them at the end of the year is equal to the twice of the difference between investment of P and ten times the investment of R. Find the profit of Q ?
Answer: C
P : Q : R = (10000 × 12) : (12000 × 10) : (7200 × 8) = 25 : 25 : 12
Now the Profit = 2 × (72000-10000) = 124000
Q’s share 25/62*12400=Rs 50000
Then profit of Q = 50000 - 12000 = Rs 38000.
