Answer:

They will need to hire 5 testers.

Step-by-step explanation:

This question can be solved using a simple rule of three.

For each 10 developers, we need 2.5 testers. So how many testers are needed for 20 developers?

10 developers - 2.5 testers

20 developers - x testes

$10x = 20*2.5$

$10x = 50$

$x = \frac{50}{10}$

$x = 5$

They will need to hire 5 testers.
