To find :

• The monthly salary of Ram

Solution :

• Let the monthly salary of ram be x

Given,

↬ Salary spend on food = 40%

↬ 40/100 × x

↬ Salary spend on food = Rs.0.4x

↬ Salary spend on house rent = 20%

↬ 20/100 × x

↬ Salary spend on house renf = Rs.0.2x

↬ Salary spend on entertainment = 10%

↬ 10/100 × x

↬ Salary spend on entertainment = Rs.0.1x

↬ Salary spend on convensiation = 10%

↬ 1/100 × x

↬ Salary spend on convensiation = Rs.0.1x

Finding total expenditure of ram :

↬ 0.4x + 0.2x + 0.1x + 0.1x

↬ 0.8x

Total expenditure of ram is 0.8x Rs.

Finding the savings of ram :

↬ Savings of ram = Salary- Expenditure

↬ 1x - 0.8x

↬ Rs.0.2x

Savings of ram is 0.2x Rs.

Finding the Monthly salary of ram :

Given,

Saving at the end of the month are 1500 Rs.

↬ 0.2x = 1500

↬ 2/10 × x = 1500

↬ x = 1500 × 10/2

↬ x = 1500× 5

↬ x = 7500 Rs.

Hence,

The monthly salary of ram is Rs.7500.

Answer 2

40% of x + 20% of x + 10% of x + 10% of x+ Rs1500 = x

(40x/100)×(20x/100)×(10x/100)(10x/100) +1500=salary

X-4/5x=1500by lcm

X/5=1500= x=7500
