Avinash is twice as fast as Bharat, and Bharat is one-third as fast as Chandra. If together they can complete a piece of work in 30 days, in how many days can Avinash, Bharat and Chandra do the work respectively?
Choices:
A) 90,180,66	B) 90,180,67	C) 90,180,61	D) 90,180,62	E) 90,180,60
Let Chandra do the work in 2x days.   Bharat can do it in 6x days and Avinash can do it in 3x days.   1/(2x) + 1/(6x) + 1/(3x) = 1/30 1/(2 ) + 1/(6 ) + 1/(3 )=
