If 12 men can do the work in 14 days

then 12 men do 1/14th part of work everyday

so one men does 1/(12)(14)=1/168th part of the work

similarly one women does 1/252th part of the work

so in one day

8 men and 16 women can do (8/168+16/252)th part of work 

so they can do 1/9th pert of work in a day

THEN THEY CAN FINISH  THE WORK IN 9 DAYS

12m=18w..... 1m=18/12w 8m=18/.12*8=12 w so 12w+16w= 28 nd then apply formula... 18*14=28*d
