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 ?

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=Rs50000
Then profit of Q=50000-12000=Rs38000.

Hence, option 3 is the correct answer.
