Please refer to the attachment for your answer

Here's some points that I want to explain:

• I have used the concept of MANDAYS. Your teacher must have taught it. If not, you can search on net.
• I have found No. of men that can do the work in terms of boys.
• Then, by using the concept of MANDAYS, I have converted one set from the two given sets into the terms of boys.
• This way, I found the answer.

I hope it helps.
