Question

Sunil completes a work in 4 days, whereas dinesh completes the work in 6 days. Ramesh works 1 1/2 times as fast as sunil. The three together can complete the work in:

Answer 1

Heyaa..

HERE IS UR ANSWER:-

Sunil's 1 day work = 1/4

Dinesh's 1 day work = 1/6

Ramesh's 1 day work = 3/2 tinmes Sunil's work 1/4 × 3/2 = 3/8

Sum of work done by all in day 1/4+1/6+3/8=
(6+4+9)/24 19/24

So to complete the work together they will need, 24/19
days.

Answer 2

productivity of Suneel  per day:  1/4

Productivity of Dinesh per day :  1/6

productivity of Ramesh per day:  1.5 * 1/4 = 3/8

Total productivity of all = 1/4 + 1/6 + 3/8  per day

                                     =   19/24

So all of them together will finish the complete work in 24/19 days
