Question

4 men and 6 women can com plete a work in 8 days, while 3 men and 7 women can complete it in 10 days. In how many days will 10 women complete it ?​

Answer 1

Step-by-step explanation:

4 Men and 6 Women take 8 days. So TOTAL WORK = 32 MD + 48 WD (where MD= Mandays, & WD = Womandays, a unit of work) ……(eqn1)

3 Men and 7 Women take 10 days. So, TOTAL WORK = 30 MD + 70 WD …. (eqn2)

Equating the total work,

32 MD + 48 WD = 30 MD + 70 WD

=> 2 MD = 22 WD

=> 1 MD = 11 WD

So, replacing man days in eqn2,

TOTAL WORK = 400 WD

Now, 10 women will complete 10 WD of work in one day.

To complete 400 WD of work,

Time needed = (400 WD)/(10 WD) = 40 Days (Answer)
