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.

Do you really have doubts with these type of questions?
These steps seem quite detailed and involve simple arithmetic.. One needs to read the question and see the answer. It will be easy to understand.

Suneel's 1 day's work=1/4
Dinesh's 1 day's work=1/6
Since Ramesh is 3/2 times faster than Dinesh,
Ramesh's 1 day's work=1/4*3/2=3/8
Working together, part of work done by them in 1 day=1/4+1/6+3/8
=(6+4+9)/24
=19/24.
Therefore they all will complete the work in 1/(19/24) days ,i.e.
24/19 days
Dinesh's 1 day's work=1/6

Ramesh is not 3/2 times faster than Suneel. That is not the correct way. Please see question. Ramesh is 3/2 times as fast as suneel.
