Question

Farid spends 5/8 of his monthly salary every month. If he spends $63.20 for house rent that is 40% his total monthly expenditure, how much is his monthly salary?​

Answer 1

$252.8

Explanation:

Total expenditure

63.20 = 40%

y = 100%

40y = 6320

Divide both sides by 40

y = 158

His expenditure is $158.00

Expenditure is 5/8 of salary

Remaining amount = 3/8

5 = 158

3 = y

474 = 5y

Divide both sides by 5

y = 94.8

Therefore 3/8 = 94.8

Salary = expenditure + remaining

S = 158 + 94.8

S = 252.8

Therefore his salary is $ 252.80
