Question

14 PUMPS OF EQUAL CAPACITY CAN FILL IN A TANK IN 6 DAYS IF THE TANKS FILLED IN 4 DAYS HOW MANY PUMPS REQUIRED

Answer 1

Answer:

This is a problem related to inverse variation since a decrease in the number of days means increase in the Number of pumps.

In 6 days Number of pump can fill a tank = 14

In 1 day Number of pump can fill a tank = 14 × 6 = 84

In 4 days Number of pump can fill a tank = 84/4= 21

the number of extra pumps needed = 21 - 14 = 7 pumps .

Hence, the number of extra pumps needed is 7.

Hope this will help u

Answer 2

Answer:

Let the extra pumprequired be x .

In6 day pump can fill a tank= 14

In 1 day pump can fill a tank= 14×6

= 84

In 4 day pump can fill a tank= 84/4= 21

The number of extra pump= 21 - 14= 7

Hence, the number of extra pump = 7
