monthly income?​

Answer 1

Given,

Her expenditure percentage = 88%

Her total savings = Rs. 3420

To find,

The amount of her monthly income.

Solution,

First of all, we have to calculate the savings percentage amount of one month.

Savings of one month :

= Total percentage - Expenditure percentage

= 100-88

= 12%

Let, the total monthly income = Rs. x

Savings of one month = x × 12/100 = x × 6/50 = x × 3/25 = Rs. 3x/25

According to the question,

3x/25 = 3420

x = 3420 × 25/3

x = 28500

Hence, her monthly salary is Rs. 28500
