Expenditure on Household = 50%
Expenditure on self = 15%
Expenditure on children = 20%
Total expenditure in month is (50 + 15 + 20)% = 85%
Savings per month is = (100 – 85)% = 15%.
15% of 30800 = (0.15 × 30800) = 4620
Therefore, Naresh saves Rs. 4620 per month.
Total Expenses 50+15+20 = 85 percent out of 100. Now remaining amount is 15%.
Therefore, 15 percent of Total earning of Naresh is
15% of 30800 = 15/100 × 30800) = 15 × 308 = Rs 4620. Hence, He saves Rs 4620 per month of Total Earning.
