Answer 2

Solution:

we are given that

Two months ago a car dealership sold 150 cars.Thirty of them were red .

Last month ,the dealership sold 200 cars.

Using unitry method , we can say that

30 cars were red out of 150.

So if there were only one car then there will be $\frac{30}{150}$ red cars.

So if there are 200 cars then there wil be $\frac{30}{150}*200=40$ red cars.

Hence there will be 40 red cars.
