Question
The income of ‘M’ is twice more than that of
‘N’. The expenditure of ‘M’ is Rs. 2000, which is twice that of ‘N’. If the savings of ‘M’ is 5 times that of ‘N’, then find the income of ‘M’.Solution
ATQ, Let the income of ‘N’ be Rs. ‘x’ Therefore, income of ‘M’ = x + 2x = Rs. 3x Expenditure of ‘N’ = 2000/2 = Rs. 1000 According to the question, 3x – 2000 = 5 × (x – 1000) Or, 3x – 2000 = 5x – 5000 Or, 2x = 3000 Or, x = 1500 Therefore, income of ‘M’ = 3x = Rs. 4500
