Question
Pipe ‘A’ can fill a 300-litre tank in 30 hours. If
pipe ‘A’ is 25% more efficient than pipe ‘C’ whereas pipe ‘B’ is 50% more efficient than pipe ‘C’, then find the time (in minutes) taken by all the given three pipes to fill the same tank together.Solution
According to Question; Efficiency of pipe ‘A’ = (300/30) = 10 litres/hour Efficiency of pipe ‘C’ = 10 ÷ 1.25 = 8 litres/hour Efficiency of pipe ‘B’ = 8 × 1.5 = 12 litres/hour Time taken by all the pipes together to fill the tank = {300/(10 + 8 + 12)} = (300/30) = 10 hours Or, time taken by all three pipes together to fill the tank = 10 × 60 = 600 minutes Â
(√845 ×19.932+ √4230 ×14.385)/(√1765 ×4.877 ) = ?
{(√2305) % of 74.69} × 15.21 - 27.89 × 44.88 + 45.12% of 2399.87
The greatest number that will divide 398,436, and 542 leaving 7, 11, and 15 as remainders, respectively, is:
2470.03 ÷ 64.98 x 39.9 = ? + 20.32
(1709.87 ÷ 38.09) + (768.11 ÷ 23.87) + (6599.81 ÷ 88.06) = ?
25.02% of 460.02+?% of 300.02=295.21
