Question
A and B enter into partnership. A invests some money at
beginning, B invests thrice the amount after 5 months and C invests double the amount after 9 months. If the annual profit be Rs.39000, then find C’s share.Solution
Let A’s investment be Rs. x. Then, ratio of capitals of A, B and C = (x × 12) : (3x × 7) : (2x × 3) ⇒  12x : 21x : 6x ⇒  4x : 7x : 2x Therefore, C’s share = Rs. 39000 x (2/13) = Rs.6000
