Question

24man can do a work in 16 days while 32 woman do same work in 24days .If 16 man and 16 woman started the work ,than after 12 days how many more men needed to finish the remanning work in 2 days?

Answer 1

Step-by-step explanation:

24 men can complete in 16 days = 100% work.

So, one man can complete in 16 days = 100/24% work.

One man can complete in 1 day = 100/(16*24) = 0.26% work

One woman can complete in 1 day = 100/(24*32) = 0.13% work.

One women and one men can complete in day = 0.26 +0.13 = 0.39% work.

So, 16 man and 16 women can complete work in 12 days = 0.39*12 *16= 75% work.

Rest Work = 25%

To complete 25% work in 2 days, no of men required = 25/(2*0.26)= 48 men.

So, Extra men = 48 - 24 = 24.
