Question

Prabhat can fill a tank with 331/2% more efficiency than priyaPrabhat can fill a tank with 331/2% more efficiency than priya

Answer 1

Answer:

Step-by-step explanation:  

33 * 1/2 %  = 1/3

16 * 2/3 %= 1 /6

Let efficiency of priya  is 3 liter / min than efficiency of prabhat = 4 liter/ min.

and efficency of Abhishek = 4 × 7/6 = 14/3 liter / min.

Sum of efficiency  of all three = 3 + 4+ 14 /3

                                               = 35 /3 liter / min

∴ Required time = 525 / 35/3 = 45 min
