Question
20 men or 40 women can complete a piece of work in 24
days. A man and a woman together complete the work and receive a total wage of Rs. 12,000. Find the difference between the wages received by them.Solution
ATQ, Let the efficiency of a man and a woman be 'M' and 'W' units/day respectively. We have, 20M × 24 = 40W × 24 So, 20M = 40W Or, (M/W) = (40/20) = 2 Required difference = {(2 - 1) /(2 + 1) } × 12000 = (1/3) × 12000 = Rs. 4,000

- What approximate value will come in place of the question mark (?) in the following question? (Note: You are not expected to calculate the exact value.)
2 (1/4)% of 7999.58 + {49.06% of 898.87} + √143.14 – 19.99% of 1499.63 - (52 - 41) = ?
√1024.21 × √624.89 ÷ 4.98 + 11.99 × 4.01 = ?
?% of 1200.22 + 319.82 = 3.99 × 295.64
? 2 + (39.99 × 10.99 + 7.01) - (39.99 × 2.99 2 + 21.99) = 21.99 × 23.01
510.11 ÷ 16.98 × 5.14 – 119.9 = √?Â
Solve the given equation for ?. Find the approximate value.
(35.86 × 15.14) ÷ 9 + √(288.89) × 4.03 = ?
...24.75% of 20.125% of 30.05% of 2196.06 = ?Â
? + 163.99 – 103.01 = 24.01 × 6.98
