8 men & 16 women can finish a Job in 6 days
∴ In 1 day the work done is of 48 men and 96 women.
12 men & 24 women can finish a job in 8 days.
In 1 day the work done is of 96 men & 192 women.
∴ 48 men + 96 women = 96 men + 192 women
26M + 20W = 52W + 20W = 72W
Let the required number of days be x.
192 : 72 = x : 5 X = \(\frac{192 \times 5}{72} = \frac{45}{3}\) = 15 days
