A and B enter into partnership. A invests some money at beginning, B invests thrice the amount after 8 months and C invests double the amount after 5 months. If the annual profit be Rs.38000, then find C’s share.
Let A’s investment be Rs. x. Then, ratio of capitals of A, B and C = (x × 12) : (3x × 4) : (2x × 7) ⇒  12x : 12x : 14x ⇒  6x : 6x : 7x Therefore, C’s share = Rs. 38000 x (7/19) = Rs.14000
