Time And Work

Vedic Maths trick to Find Time And Work Problems.

24 man can complete a work in 27 days . 7 day after they started working with 44 more man. How many day they now take to complete the remaining work.

(24 * 27) man can complete a work in 1 days .

(648) man in 1 days = 1 work .

There for 1 man in 1 day's = 1 / 648.

There for 24 man in 7 days = 1 / 648 * 24 * 7.

= 168/648

= 7 / 27

Remaining work = 1 - 7/27 = 20/27 work

68 man in 1 days = 68 / 648 work = 17 / 162 work

162 / 17 days = 1 work

20/27 * 162 / 17 days = 20/27 work

= 3240 / 459 days

= 120 / 17 days

120 / 17 days they now take to complete the remaining work.
