A. 12 days
B. 14 days
C. 16 days
D. 18 days
3 men does same work as 4 women in 43 days.
multiply 3 and 4 and 43 for a supposed amount of total work (516).
Now calculate how much work is done by 3 men in one day by dividing 516 by 43 (12). Then calculate one man work in one day by dividing 12 by 3 (4).
Same (12) amount of work is done by 4 women in one day. so one women does 12/4 (3) in one day.
now see there are 7 men and 5 women in the final team.
total amount of work in one day will be
7(4)+5(3) = 43
Now divide total work (516) by total work in one day (43) to get the answer (12)
Correct Answer: A. 12 days ✔
