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
