Best answer
(Capital of A): (Capital of B)`=2:3=4:6`
Also, (capital of B): (capital of C)`=2:5=6:15`
`:.` Capital of A: Capital of B: Capital of `C=4:6:15`
`:.` Part of capital of `A=A/(4+6+15)=4/25`
Part of capital of `B=6/25`
Part of capita of `C=15/25`
So from Rs. 1000 A, will get Rs. `1000xx4/25=Rs. 160`
from Rs. 1000, B wil get `Rs. 1000xx6/25=Rs. 240` and from Rs. 1000, C will get Rs. `1000xx15/25=Rs. 600` Hence the profit of A,B and C are Rs. 160, Rs. 240 and Rs. 600 respectively.
