Answer» Correct Answer - Option 5 : Quantity A = Quantity B or No relation. Quantity A: E and F together fill a cistern in 30 minutes. Pipe E alone can fill it in 45 minutes Time taken by F alone to fill cistern Calculation: Cistern filled in 1 minute by E and F = 1/30 Cistern filled by E in 1 minute = 1/45 Time taken by pipe F alone to fill a cistern = [(1/30) – ( 1/45)] = [( 3 -2)/90] = 1/90 = 90 minutes Quantity B: 90 minutes ∴ Quantity A = Quantity B |
