Let the incomes of 'A' and 'B', in 2020, be Rs. '8x' and Rs. '5x', respectively. Let the expenses of 'A' and 'B', in 2020, be Rs. '5y' and Rs. '3y', respectively. Savings of 'A' in 2020 = Rs. (8x - 5y) Savings of 'B' in 2020 = Rs. (5x - 3y) ATQ: (8x - 5y) - (5x - 3y) = 5000 Or, 3x - 2y = 5000 ....... (I) Expenses of 'A' in 2021 = 5y X 1.12 = Rs. '5.6y' So, savings of 'A' in 2021 = Rs. (8x - 5.6y) ATQ: (8x - 5.6y) - (5x - 3y) = 2000 Or, 3x - 2.6y = 2000 ...... (II) On subtracting equation (II) from equation (I), we have; 0.6y = 3000 So, y = 5000 So, expenditure of 'B' in 2020 = 3 X 5000 = Rs. 15,000Â
√2703.88 × √784.15 – 26² = ? - (34.85)²
√92.10 + √256.30 + 60.78% of (420.90 + 19.36% of 140.25) = ?
25.09 × (√15 + 19.83) = ? of 19.87 ÷ 4.03Â
Direction: Please solve the following expression and choose the closest option
52.08% of 645.92 + 1840% of 47.96 = ?
19.99% of 79.98 = ?2– 159.99% of 12.5
19.97% of 3/5 ÷ (1 ÷ 74.99) = ?
30.22% of (61.9 × 5.01) + 69.97 =?Â
1199.98 ÷ 40.48 × 20.12 = ? × 3.16
88% of 900.23 + 74.99 = ?
