ATQ, Sum of incomes of 'X' and 'Y' = 45,000 × 2 = Rs. 90,000 Sum of expenditures of 'X' and 'Y' = 34,000 × 2 = Rs. 68,000 So, sum of savings of 'X' and 'Y' = 90,000 - 68,000 = Rs. 22,000 Let the savings of 'Y' be Rs. '100y' So, savings of 'X' = 1.20 × 100y = Rs. '120y' Now, 100y + 120y = 22,000 Or, 220y = 22,000 So, 'y' = 100 Therefore, savings of 'X' = 120 × 100 = Rs. 12,000
