Q13. Five workers can complete a work in 8 hrs, assuming that every worker works with same efficiency. They started working at 10.00 a.m. If after 4.00 p.m., one worker is removed from the group every hour, what is the time when they will finish the work? 6.00 p.m.
7.00 p.m.
4.00 p.m.
8.00 p.m.

Solution:
let efficiency of each worker is x unit/hr
Let total work = 8 × 5 × x = 40x units
ATQ 40x = (5x × 6) + (4x × 1) + (3x × 1) + (2x × 1) + (1x × 1)
After 10 hours i.e. at 8:00 pm work will be completed
Let total work = 8 × 5 × x = 40x units
