inappropriate (Question: 196631.0 )

Many questions are wrong, but still attempt is made by toprankers to get the wrong answers seem correct by using any values and inputs. It is wrong on the part of toprankers.
They are providing many tests quantitatively for the sake of money, but focus must also be given on the accuracy of the correct answers.

Question:
A, B and C can complete a work separately in 24, 36 and 48 days respectively. They started together but C left after 4 days of start and A left 3 days before the completion of work. In how many days will the work be completed ?
Options:
A) 20 days 
B) 18 days 
C) 16 days 
D) 15 days
Solution:

Ans(d);

In 4 days A, B, C complete 4*(1/24+1/36+1/48)=13/36 of the work

work left: 23/36

let A work for d-3 days after the 1st 4 days, let B work for d days aftre the 1st 4 days

(d-3)/24+d/36=23/36

=>(60d-108)/36*24=23/36

=>d=11

Total number of days taken: 4 days+ 11 days (after C left)=15 days.
