Answer» Correct Answer - Option 1 : 120000 Given: The rise in the income of A is 20%. He now spends Rs. 20,000 more which is double of the previous expenditure, keeping his savings same. Formula Used: Ratio of Profit = ratios of product of Amount invested and time Income – savings = expenditure Calculation: Let initial income be Rs. 5x New income be Rs. 6x Let expenditure initially be Rs. y New expenditure = Rs. (y + 20,000) ATQ, ⇒ y + 20,000 = 2y ⇒ y = 20,000 Since savings is same ⇒ 5x – y = 6x – (y + 20,000) ⇒ 5x – 20,000 = 6x – y – 20,000 ⇒ 5x – 20,000 = 6x – 40,000 ⇒ x = 20,000 His increased income = 6x = Rs. (6 × 20,000) = Rs. 1,20,000 ∴ His increased income is Rs. 1,20,000

The rise in the income of A is 20%. He now spends Rs. 20,000 more which is double of the previous expenditure, keeping his savings same. Find the increased income (Rs.).1. 1200002. 1900003. 1600004. 110000

Answer» Correct Answer - Option 1 : 120000

Given:

The rise in the income of A is 20%.

He now spends Rs. 20,000 more which is double of the previous expenditure, keeping his savings same.

Formula Used:

Ratio of Profit = ratios of product of Amount invested and time

Income – savings = expenditure

Calculation:

Let initial income be Rs. 5x

New income be Rs. 6x

Let expenditure initially be Rs. y

New expenditure = Rs. (y + 20,000)

ATQ,

⇒ y + 20,000 = 2y

⇒ y = 20,000

Since savings is same

⇒ 5x – y = 6x – (y + 20,000)

⇒ 5x – 20,000 = 6x – y – 20,000

⇒ 5x – 20,000 = 6x – 40,000

⇒ x = 20,000

His increased income = 6x = Rs. (6 × 20,000) = Rs. 1,20,000

∴ His increased income is Rs. 1,20,000
