Answer:
given work done by 3 women= work done by 5 girls
work doe by 1 women= work done by 5/3 girls
therefore work done by 7 women and 11 girls= work done by 35/3+11= 68/3 (girls)
since 5 girls can complete the work in 17 days so 1 girl can complete in 85 days then 7 women and 11 girls can complete the work in= 85/68/3=3 3/4 days.
or
since 3 women work= 5 girls work
1 women's work= 5 girls work
hence, 7 women's work= 5/3*7= 35/3
7 women's and 11 girls work= 35/3+11
= 35+33/ 3= 68/3
since 5 girls can do the work in 17 days,
hence, 1 girl can do the work in ( 17*5 days)= 85 days
hence, 68/3 girls can do the work in 85/68/3 days= 85*3/68= 255/68= 15/4
= 3 3/4 days
