Question
Anil alone can finish some work in 50 days. Anil and
Aman completed the work together and earned Rs. 9,000 as wage. If Aman's wage share is Rs. 3,600, then find the time taken by Aman to finish the work alone.Solution
ATQ, Share of Anil = 9000 - 3600 = Rs. 5,400 We know that wages are distributed in the ratio of efficiency when work is done together. So, the ratio of efficiency of Anil and Aman = 5400:3600 = 3:2 Therefore, the ratio of time taken by Anil and Aman to complete the work alone = 2:3 Therefore, the time taken by Aman to finish the work = 50 x (3/2) = 75 days
157.78% of 4820 + 92.33% of 2840 = ? + 115.55% of 1980
(23.99)2 – (17.99)2 + (1378.88 + 44.88) ÷ ? = 607.998
24.99 × 32.05 + ? - 27.01 × 19.97 = 29.99 × 27.98
(804/65) ÷ (11/798) × (129/131) = ?
Direction: Please solve the following expression and choose the closest option
(15.87% of 79.98 + 19.69% of 64.22) × 4.83 = ?
(? + 11.86) X 14.89 = 19.89% of 2399.89
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.)...
Solve the following expression and calculate the approximate value.
398% of 388 + 129% of 323.89 – 430.93
`sqrt(1297)` + 189.99 =?
