Answer 2

Step-by-step explanation:

Men are 16/12 = 1,33 times more efficient than

woman

If men were only doing the job then

(12 + 16/1,33) x 172 ? man days

12 + 12 x 173 = 4152 man days

what this means is that 12 men can do the job of

16 women

so then converting women hours to men hours

(21 + 15/1,33) x ? Days = 4152

? days = 4152/32,25 = 128,75 of 128 and 3/4 days
