let m=daily rate of 1 man
10*4m=1
m=1/40
let w=daily rate of 1 woman
10(2/40+3w)=1
w=1/60
let d=number of days for 3 men and 3 women
d(3/40+3/60)=1
d=8 days

Can be solved just by seeing answers, IF 2m+2W take 10 days, it obviously will take less time for 3M+3W => Check for option less that 10 days(A).

3 men and 3 women will definitely get the job done in less time than 2 men and 3 women, who can finish the job in 10 days. The only answer choice that is less than 10 days is A, 8 days.

Answer: A

Step 1.
Rate of work for man can be calculated with data in stem.
Step 2.
Rate of work for man and women combined is also given in stem.
Step 3.
Thus rate for women to be calculated as rate of women=Rate of both - Rate of man
Step 4.
Since rate of man and women are known we can calculate rate for 3 men and 3 women and thus time required( time = 1/Rate)

All is done in above post by gracie
