Question

A and b invested rs. 30,000 and rs. 40,000 respectively in a business for one year . If they earned rs. 7,700 at the end of one year, then find b's profit.

Answer 1

the ratio of their investment is 30000: 40000 means 3: 4...as their profit was 7700 at the end of the year..... so the profit of b is {4/(3+4) }×7700=4400
