Ramesh has 20% savings with him from his monthly salary. If expenditure on clothing is 25% of overall expenditure and his total expenditure except clothing is 3600 then find his saving.

Total expenditure = 80% of salary

Expenditure excluding clothing

$= 80{ m{\% }} - frac{{25}}{{100}} imes 80{ m{\% }} = 60{ m{\% }}$ ???????? ????????????????????????????

Ramesh savings = $frac{{3600}}{{60}} imes 20 = 1200$ Rs.
