X can do ¼ of a work in 10 days, Y can do 40% of work in 40 days and
Z can do 1/3 of work in 13 days. Who will complete the work first?
Z
X
Y
X,Y
Explanation:
Whole work will be done by X in 10*4 = 40 days.
Whole work will be done by Y in (40*100/40) = 100 days.
Whole work will be done by Z in (13*3) = 39 days
Therefore, Z will complete the work first.
Whole work will be done by X in 10*4 = 40 days.
Whole work will be done by Y in (40*100/40) = 100 days.
Whole work will be done by Z in (13*3) = 39 days
Therefore, Z will complete the work first.
