Answer» Let us ASSUME that money invested by A = 7x ⇒ money invested by B = 4x ⇒ A keeps his money for 4 months = 7x × 4 A takes out 1/7th of his money ⇒ Investment for REMAINING 8 months = 7x × 6/7 × 8 = 6x × 8 ⇒ A’s total investment = 7x × 4+6x × 8 = 28x+48x = 76x ⇒ B keeps his money for 5 months = 4x × 5 = 20x after that, B takes out 1/6 th of his money ⇒ Investment of B for remaining 7 months = 4x × 5/6 × 7 = 70x/3 ⇒ total investment by B = 20x+70x/3 = 130x/3 C invests same money as B’s initial money for 4 months ⇒ Investment of C for 4 months = 4x × 4 = 16 x A : B : C will be, ⇒ 76x : 130x/3 : 16x ⇒ 228x : 130x : 48x ⇒ 228 : 130 : 48 ⇒ 20% of profit goes to C, ⇒ 126875 × 20/100 = 126875/5 = Rs. 25375 Remaining profit which should be divided AMONG 3 of them will be, ⇒ 126875 - 25375 = Rs. 101500 Finally B’s share will be, ⇒ 101500 × 130/(130+228+48) ⇒ 101500 × 130/406 ⇒ 50750 × 130/203 ⇒ 7250 × 130/29 ∴ 250 × 130 = Rs. 32500 |
