Question
Income of A is twice the income of B. B and A spend 40%
and 50% respectively of their incomes. Find the savings of A, if B saves Rs. 60000 in a month.Solution
Let, income of B be Rs. ‘x’ Expenditure of B = 0.4x So, 0.6x = 60000 x = Rs. 100000 Income of A = 2 × 100000 = Rs. 200000 Savings of A = 50% of 200000 = Rs. 100000
