Question

A man completes work in 14 days..Two men complete work in 10 days.In how many days the second person would complete work?

Answer 1

Here's your answer!!

_____________________________

Let the two man be 'A' and 'B'

A can complete the work in 14 days.

One day work of A =
$= > \frac{1}{14}$

Two men can complete the work in 10 days

One day work of (A+B)=
$= > \frac{1}{10}$

Let the time taken by B to complete the work be x.

A/q

$= > \frac{1}{14} + x = \frac{1}{10}$

$= > x = \frac{1}{10} - \frac{1}{14}$

$= > x = \frac{7 - 5}{70}$

$= > x = \frac{2}{70}$

$= > x = \frac{1}{35}$

Hence,

'B ,the second man' can complete the work in 35 days.
