Question

b) A pipe fill 7/10 parts of a tank in 1 hour and another pipe can fill 9/15 parts of the same tank in 1 hour. Which pipe can fill the tank faster? ​

Answer 1

Given:

Fraction of tank filled by pipe 1 in 1 hour= 7/10

Fraction of tank filled by pipe 2 in 1 hour= 9/15

To find:

The pipe which fills the tank faster

Solution:

For Pipe 1-

7/10 tank is filled in 1 hour

so, 1/10 tank is filled in 1/7 hour

so 10/10 (completely filled) tank is filled in

1/7 X 10 hours

= 10/7

= 1.42 hours

For pipe 2-

9/15 tank is filled in 1 hour

so, 1/15 tank is filled in 1/9 hour

so 15/15 (completely filled) tank is filled in

1/9 X 15 hours

= 15/9 hours

= 1.66 hours

Hence, Pipe 1 fills the tank faster than pipe 2.
