Your description is a little unclear, "at second day" when A quits. Assuming A quits AT THE END OF SECOND DAY, the situation goes like this:
Rates as tasks per day
A: 1/4
B: 1/5
C: 1/6
Amount of task completed by end of two days:
Amount of task for B and C to do:
The task rate for B and C together is (1/5+1/6) tasks per day.
Using Rate*Time=Tasks, we can find the unknown number of days for B and C to finish the remaining amount of task.
That uses d = the number of days for B and C to do the remaining task portion.
(Leaving the rest of symbolic steps to solve for d, to you).
