To solve this

QUESTION

Eight men can do a piece of work in 12

days. How long will 6 men take to do the

same work if they work at the same rate?

SOLUTION

Let X be thr time taken for 6 men to work at the same rate

Looking at the question, it is an indirect proportion

because as the number of men increases, the time taken to do the work decreases

So therefore;

8 men = 6 men

X days = 12 days

cross-multiply

6 x X = 12 x 8

6X = 96

divide both-sidde of the equation by 6

6X/6 = 96/6

X = 16 days

Therefore, it takes 16 days for 6 men men to do the work at the same rate.
