Question

There are 2 seats on the left side of a plane and three seats on the right. If there are 45 seats on the right, how many are on the left?

Answer 1

30 seats

Explanation:

For every row, there are 2 seats on the left and 3 seats on the right.

If there are 45 seats total on the right side, then there must be 45/3 = 15 rows. Therefore, there are 15*2= 30 seats on the left.
