Rahul spends some part of his income and saves the remaining part. The ratio of his expenditure and saving is 5 : 4. If Rahul's income is Rs. 36000, then what will be his expenditure ?

Rs. 15000 Rs. 25000 Rs. 20000 Rs 16000

Rs. 20000

Expenditure = 5R Saving = 4R Income = 5R + 4R = 9R = 36000 ⇒ 1R = 4000 Expenditure = 5R = 5 x 4000 = 20000
