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.
Answer & explanation
Correct answer: option 3
Income - saving = Expenditure.
Income ⇒ 4 : 5
Expenditure ⇒ 2 : 3
ATQ
⇒ \(\frac{4R -300}{5R - 300}\) = \(\frac{2}{3}\)
⇒ 12 R - 900 = 10R - 600
⇒ 2R = 300
⇒ 1R = 150
Hence,
Income of Junaid = 5 × 150 = 750/-
