A started a business with rs.2, 70, 000 and was joined by b three months afterwards. how much money did b invest if the profit share of a at the end of the year was three- fifth of the total profit?

Let us assume the profit to be x

and the profit a will be 3/5 x

profit of b will be x – 3/5 x

= 2/5 x

Now we will find the ratio of profit

a : b = 3/5x : 2/5 x

a / b = 3/5 × 5/2 = 3 : 2

270000 (this is the contribution of A)

2/3 × 270000 = 180000 (this is the contribution of B)

Rs: 180000
