Question

14 pumps of equal capacity can fill a tank in 6 days. If the tank has to be filled in 4 days , find the number of extra pumps needed​

Answer 1

Answer:

Extra pumps required: 7.

Step-by-step explanation:

Given: 14 pumps of equal capacity can fill a tank in 6 days.

=> 6 days needed by 14 pumps to fill the tank.

=> If the tank is to be filled in 1 day, 14×6 pumps would be needed. (also the total capacity of tank)

=> If the tank is to be filled in 4 days, 21 pumps would be needed.

Therefore, 21-14 =7
