    Solution

    ATQ, Sum of incomes of 'P' and 'Q' = 50,000 × 2 = Rs. 1,00,000 Sum of expenditures of 'P' and 'Q' = 32,000 × 2 = Rs. 64,000 So, sum of savings of 'P' and 'Q' = 1,00,000 - 64,000 = Rs. 36,000 Let the savings of 'Q' be Rs. '100y' So, savings of 'P' = 1.40 × 100y = Rs. '140y' Now, 100y + 140y = 36,000 Or, 240y = 36,000 So, 'y' = 150 Therefore, savings of 'P' = 140 × 150 = Rs. 21,000
