Question

Hari can sort the newspaper in 14minutes but if Ramesh helps they can sort the newspaper in 9 minutes how long would it take Ramesh to sort the newspaper alone

Answer 1

Ramesh would take 25.2 minutes to sort the newspaper.

Step-by-step explanation:

As given in question that Hari can sort the newspaper in 14 minutes.

Ramesh and Hari together can sort the newspaper in 9 minutes.

We have to find how long Ramesh would take to sort the newspaper.

So,

Hari can sort the newspaper in 1 minute = $\frac{1}{14}$

Ramesh and Hari together can sort the newspaper in 1 minute = $\frac{1}{9}$

Therefore,

Work done by Ramesh alone:

= $\frac{1}{9}\ - \frac{1}{14}$

= $\frac{14\ -\ 9}{126}$

= $\frac{5}{126}$

= $\frac{1}{25.2}$

Hence, Ramesh would take 25.2 minutes to sort the newspaper.
