12 men can complete any work in 36 days. 18 women can complete the same piece of work in 60 days. 8 men and 20 women work together for 20 days. If only the women were to complete the remaining work in 4 days, then how many women would be required?	Select the correct option
A) 60  B) 74  C) 68  D) 75  E) 70
1 Man, 1 Day work=1/(12*36)   1 Woman, 1 Day work=1/(18*60)   So 8 men and 20 women's 20 days work= 20[ 8/(12*36) + 20/(18*60) ] =20/27   Remaining work= 7/27   If remaining work is to be completed by 'x' women in 4 days, then 4*x/(18*60)= 7/27   =&gt; x=(7*18*60)/(27*4)=
