a
Total Number of male workers in Accenture=96
Total Number of female workers in Accenture=24
male efficiency=1
female efficiency=3
Total Work they done in one day=Number of persons×efficiency
Total Work done by male engineers in one day =96×1=96
Total Work done by female engineers in one day =24×3=72
Total number of projects=4500
They work alternately (i.e. male engineers work alone for first day and female engineers work alone for next day )
So in Two days the total work done will be 96+72=168
So for whole project completion=4500/168×2
=9000/168=53 4/7 days
