Aman spends 75% of his income.If his income increases by 28% and his expenditure increases by 20%, then what is the increase or decrease percentage in his savings ?
Answer & explanation
Correct answer: option 2
Let income of a man be 100 Rs.
Expenditure = 75 Rs.
Saving = 25 Rs.
New income = 100 × \(\frac{128}{100}\) = 128 Rs.
New expenditure = 75 × \(\frac{120}{100}\) = 90 Rs.
New saving = 128 - 90 = 38 Rs.
Percent increase in saving = \(\frac{13}{25}\) × 100
= 52%
