Answer» Correct Answer - Option 3 : 14000 Given: If earning of A increases by 80%, he will save 50% of his income. B’s income is Rs. 1000 less than the new income of A. B saves Rs. 12000 and spends 25% more than he saves. Formula Used: Ratio of Profit = Ratios of product of invested amount and time Income – expenditure = savings Calculation: Let 100x be the initial earning of A New earnings of A = 180x Savings of A = 180x × ½ Savings of A = 90x Income of B = 180x – 1000 B saves Rs. 12000 B spends = Rs. (12000 × 5/4) = Rs. 15000 ⇒ 180x – 1000 – 15000 = 12000 ⇒ x = 1400/9 Savings of A = 90x = Rs. (90 × 1400/9) = Rs. 14000 ∴ A’s savings is Rs.14000

Answer» Correct Answer - Option 3 : 14000

Given:

If earning of A increases by 80%, he will save 50% of his income.

B’s income is Rs. 1000 less than the new income of A.

B saves Rs. 12000 and spends 25% more than he saves.

Formula Used:

Ratio of Profit = Ratios of product of invested amount and time

Income – expenditure = savings

Calculation:

Let 100x be the initial earning of A

New earnings of A = 180x

Savings of A = 180x × ½

Savings of A = 90x

Income of B = 180x – 1000

B saves Rs. 12000

B spends = Rs. (12000 × 5/4) = Rs. 15000

⇒ 180x – 1000 – 15000 = 12000

⇒ x = 1400/9

Savings of A = 90x = Rs. (90 × 1400/9) = Rs. 14000

∴ A’s savings is Rs.14000
