A person can save 25% of his income. If his income increases by 20% and still he saves the same amount as before, the percentage increase in his expenditure is ______.

$26\frac{2}{3}$

Let income of Men = 100x

Saving = 25% of 100x = 25x

Expenditure = 75x

New Income = 100x + 20% of 100x = 120x

Saving(same)  = 25

New Expenditure = 120x - 25x = 95x

Increase percentage in Expenditure= \(\frac{95x - 75x }{75x}\) × 100

= $26\frac{2}{3}$
