Question

Hari+can+sort+the+newspapers+in+14+minutes but if Ramesh helps they can sort the newspapers in9 minutes

Answer 1

Ramesh alone can sort newspaper = $\frac{125}{5}$ minutes

= 25$\dfrac{1}{5}$

Step-by-step explanation:

Hari's 1 minute's sort newspaper = $\dfrac{1}{14}$ and

(Hari's + Ramesh's) 1 minute's sort newspaper = $\dfrac{1}{9}$

∴ Ramesh's 1 minute's sort newspaper

= (Hari's + Ramesh's) 1 minute's sort newspaper - Hari's 1 minute's sort newspaper

= $\dfrac{1}{9}$ - $\dfrac{1}{14}$ and

= $\frac{(14 - 9)}{14 × 9}$ minutes

= $\frac{5}{14 × 9}$ minutes

∴ Ramesh alone can sort newspaper = $\frac{125}{5}$ minutes

= 25$\dfrac{1}{5}$
