Question

Team one had twice as many workers as team two. As a result of increased productivity the number of workers in team one was reduced by 5 and the number of workers in team two was reduced by 2. How many workers are there in each team now if there are 7 more workers in team one?

Answer 1

15 workers in Team 1 and 8 in Team 2.

Explanation:

Let the number of workers that were in team 2 = x, then the number in Team 1

would have been 2x.

So later we had 2x - 5 workers in Team 1 and x - 2 in Team 2.

Now there are 7 more workers in Team 1 so we have the equation

2x - 5 - (x - 2) = 7

x - 5 + 2 = 7

x = 10 .

So now there are 20 - 5 = 15 workers in Team 1 and 10 - 2 = 8 in Team 2.
