The monthly income of Ajay and Vikram is in the ratio of 5:4 and their monthly expenditure is in the ratio of 4:3. If each of them saves Rs.3000 per month, the income of Vikram is:

Explanation

Let monthly income of Ajay = 5x And monthly income of Vikram = 4x Let monthly expenditure of Ajay = 4y And monthly expenditure of Vikram = 3y Both of them save Rs.6000 each per month, Therefore, => 5x – 4y = 3000 ----- (i) => 4x – 3y = 3000 ------ (ii) By solving both the equations we get, => x = 3000 => y = 3000 Monthly income of Vikram = 4x = 4 × 3000 = Rs. 12000 IBPS RRB Scale I 2021 Prelims Memory Based Paper Direction:- Study the table carefully and answer the following questions.
