The income of Prashant and Junaid are in the ratio of 4 : 5. If each of them saves Rs. 300 per month, then the ratio of the expenditure becomes 2 : 3. Find the income of Junaid.

750

Income - saving = Expenditure.

Income ⇒ 4 : 5

Expenditure ⇒ 2 : 3

ATQ

⇒ \(\frac{4R -300}{5R - 300}\) = \(\frac{2}{3}\)
