Question

.Ravina spends 90% of the money that she receives every month and saves 100 rupees. How much money does she gets monthly​

Answer 1

Let her monthly income be Rs x.

Savings = Rs 120

Expenditure = 90% of x = (90)/100 x` =

(9x)/10`

Savings = = Total monthly salary - Expenditure

= x= 10 x 120 = 1200

Thus, total monthly salary Rs 1200.
