Question

Mohan takes 9 hours to mow a large lawn. He and Sohan together can
mow in 4 hours. How long will Sohan take to mow the lawn if he works
alone? Guys please answer fast......... ​

Answer 1

☆Answer☆

Given

Mohan can mow a lawn in 9 hours.

Work done by Mohan in 1 hour

$= > \frac{1}{9}$

Mohan and sohan mow it together = 4 hours .

Work done by them together in 1 hour

$= > \frac{1}{4}$

Work Done By Sohan in 1 hour = ( work done by both in 1 hour ) - (Work Done by Mohak in 1 hour )

$= \frac{1}{4} - \frac{1}{9} = \frac{9 - 4}{36} = \frac{5}{36}$

Therefore time taken by Sohan to complete the work

$= > \frac{1}{ \frac{5}{36} } = \frac{36}{5} \: hours$

☆Hope it Helps☆
