Question
Pipe ‘A’ can fill a 210-litre tank in 15 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’ = (210/15) = 14 litres/hour Efficiency of pipe ‘C’ = 14 ÷ 1.25 = 11.2 litres/hour Efficiency of pipe ‘B’ = 11.2 × 1.5 = 16.8 litres/hour Time taken by all the pipes together to fill the tank = {210/(14 + 11.2 + 16.8)} = (210/42) = 5 hours Or, time taken by all three pipes together to fill the tank = 5 × 60 = 300 minutes Â
(25.111 % of 200) × 26 ÷ 12.99 – 18.88 × 15.82 + 150.33% of 3√ 4917 = ? – 200
...A man purchases some pens at a rate of 4 for ₹14 and an equal number at a rate of 5 for ₹18. He sells all the pens at a rate of 6 for ₹20. What is...
?% of 320 - 69 = 123
7(1/2) – 3(5/6) = ? − 2(7/12)
192.251 + 326.233 + 125.021 + 19.273 = ?
√4761 ÷ 23 + √12769 = ? × 58
? = 80% of 30% of (50 × 150) + 400
{5% of (20 × 25) + 6% of (30 ×35)} ÷ 11 = ?Â
