Answer» Correct Answer - Option 4 : 1,10,000 Given: Ratio of expenditure on grocery, clothes and education = 5 : 7 : 10 Percentage of expenditure of monthly income = 60% Amount spent on grocery = Rs. 15,000 Calculation: Let the amount spend on grocery, clothes and education be ‘5x’, ‘7x’ and ‘10x’ ⇒ Total expenditure = 5x + 7x + 10x = 22x According to the question, ⇒ 5x = 15000 ⇒ x = 3000 ⇒ Total expenditure = 22 × 3000 = Rs. 66,000 Also, this is 60% of her total income ⇒ 60% of Income = 66000 ⇒ 60/100 × Income = 66000 ⇒ Income = 66000 × 100/60 ⇒ Income = Rs. 1,10,000 ∴ Her monthly income is Rs. 1,10,000

Answer» Correct Answer - Option 4 : 1,10,000

Given:

Ratio of expenditure on grocery, clothes and education = 5 : 7 : 10

Percentage of expenditure of monthly income = 60%

Amount spent on grocery = Rs. 15,000

Calculation:

Let the amount spend on grocery, clothes and education be ‘5x’, ‘7x’ and ‘10x’

⇒ Total expenditure = 5x + 7x + 10x = 22x

According to the question,

⇒ 5x = 15000

⇒ x = 3000

⇒ Total expenditure = 22 × 3000 = Rs. 66,000

Also, this is 60% of her total income

⇒ 60% of Income = 66000

⇒ 60/100 × Income = 66000

⇒ Income = 66000 × 100/60

⇒ Income = Rs. 1,10,000

∴ Her monthly income is Rs. 1,10,000
