$\mathfrak{The\:Answer\:is}$


8/3 Days = 2 Days 16 Hrs

We are given that 33 men do the work in 1616days.
So, Work done by 33 men in 1 day =1/16=1/16
Now, Work done by 11 man in 1 day = 1/(16∗3)=1/481/(16∗3)=1/48 days.

Similarly, Work done by 1 woman in 1 day can be found out and it is 1/641/64

Now, Work done by 12 men in 1 day = 12/48=1/412/48=1/4

Work done by 8 women in 1 day =8/64=1/88/64=1/8.

Now, Work done  12 men and 8 women in 1 day = 1/4+1/8=3/81/4+1/8=3/8

So, 12 men and 8 men do 3/83/8 of work in 1 day.

So, to complete the work, it will take them 8/38/3 days. We Just inverse the fraction found above.

So, the total time taken is 8/3 days = 2 Days 16 Hrs
