Question
A can do a piece of work in 40 days. A is 25% more
eicient than B. In how many days the work gets completed when both of them work together?Solution
Efficiency of A = 1/40 Efficiency of B = (1/40) × (1/1.25) = 1/50 Time taken by B to complete the work = 50 days Let the total amount of work = 200 units Amount of the work done by A in one day = 200/40 = 5 units Amount of the work done by B in one day = 200/50 = 4 units Time taken by both to complete the work = (200/9) days

1299.999 ÷ 325.018 × 24.996 = ?
What approximate value should replace the question mark?
99.95 − √529 × 3 + 1439.80 ÷ 12.02 = ?
619.97 ÷ 20.01 X 124.99 ÷ 24.91 = ?
124% of 620.99 + 11.65% of 1279.23 = ?
What approximate value should replace the question mark?
9.96% of 1200.10 − 25% of 4800 = ? − 7000.20
