A, B, C are partners. A receives $\frac{2}{3}$ of the profit, B and C dividing the remainder profit equally. If A's share of profit increased by ₹400 when the rate of profit rises from 5 to 7%. What is the share of B in profit ?

₹5,000

Ratio of profit of A : A + B + C = 2 : 3  & B : C = 1 : 1

So, A : B : C = 4 : 1 : 1

According to question ,

4R of 7% of profit - 4R of 5% of profit = 400

4R of 2% of profit = 400

1R = 5000

Share of B' profit = 1R = 5000

The correct answer is option (2) : ₹5,000
