Answer 1

Answer:

Let's calculate :

Expenditure on food + Expenditure on house rent + Expenditure on Entertainment + Expenditure on conveyance = Monthly Expenditure

i.e. 40% + 20% + 10% + 10% = 80%

Therefore, Radha's monthly expenses are 80% of her salary.

i.e. 100% - Monthly expenses = Monthly saving

So, 100% - 80% = 20%

Hence, Radha saving is 20% of her Monthly Salary … (1)

Radha's saving at the end of the month is 1500 rupees … ( given)(2)

So, Radha's Monthly Saving is 20%(from point 1) and her Monthly Saving is 1500( from point 2)

1500 rupees is 20% saving of Radha's Monthly Salary so 10% saving of Radha's salary is 750 rupees

i.e. 10% of Radha's Monthly saving × 10 = Radha's Monthly Salary.

750 × 10 = 7500 rupees

Therefore Radha's Monthly Salary is 7500 rupees.
