Question
Kailash used to spend 85% of his income. When his income increased by 36% his expenses also increased by 40% of his earlier expenses. How much percentage of his earnings he saves now?
Solution
Let the Kailas's income be ₹ x.
Kailash used to spend 85% of his income.
∴ Money spent = `x xx 85/100`
= ₹ `(85x)/100`
Income − Expenditure = Savings
`x - (85x)/100` = Savings
∴ Savings = `(15x)/100`
Kailash's income increased by 36%.
∴ Kailash's increased income = `x + x xx 36/100`
= `x + (36x)/100`
= ₹ `(136x)/100`
Kailash expenses increased by 40%.
∴ Increased expenses of Kailash = `(85x)/100 + (85x)/100 xx 40/100`
= `(85x)/100 + (34x)/100`
= ₹ `(119x)/100`
Kailash's current savings = Income - Expenditure
= `(136x)/100 - (119x)/100`
= ₹ `(17x)/100`
Kailash's percentage of savings = `"Savings"/"Income" xx 100`
= `(17x)/100 + (136x)/100 xx 100`
= `(17x)/100 + 100/(136x) xx 100`
= 12.5
Kailas now saves 12.5 percent of his earnings.
