The incomes of Kesari and Dileep are in the ratio of 7:5 and their expenditure are in the ratio of 5:3. If the income of Kesari is thrice the expenditure of Dileep, then what is the ratio of savings of Kesari and Dileep?
Answer & explanation
Correct answer: option 2
Kesari : Dileep

exp. 5y : 3 y
3y × 3 = 7x
9y = 7x ⇒ \(\frac{x}{y}\) = \(\frac{9}{7}\)
income 7 × 9 : 5 × 9
exp. 5 × 7 : 3 × 7
