5 girls do the same work?

Please give explanation​

Answer 1

Answer:32 days

Step-by-step explanation:

With reference to completion of work 5 women = 8 girls

So 10 women = 16 girls

8 girls can complete in 84 days then

10 women and 5 girls

10 women = 16 girls + 5 girls = 21 girls

So 8 girls can complete in 84 days

Then 21 girls = 8×84/21 = 32 days
