with explaination​

Answer 1

Answer:

Expenditure :

Food→ 40%

House Rent→ 20%

Entertainment→ 10%

Conveyance→ 10%

Total expenditure = 80%

Savings = 100% - 80% =20%

20%→ 1500

1%→ 150020

Salary(100%)→ 150020×100

= Rs.7500

Step By Step Explanation:

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, Ram's monthly expenses are 80% of his salary.

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

So, 100% - 80% = 20%

Hence, Ram saving is 20% of his Monthly Salary … (1)

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

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

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

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

750 × 10 = 7500 rupees

Therefore Ram's Monthly Salary is 7500 rupees.
