Question

There are 2 seats on the left side on each row and 3 seats on the right side there are 90 seats on the right side of the plane how many seats are there all together ?

Answer 1

Answer:

Total number of seats on plane = 150 seats

Step-by-step explanation:

Number of seats on right = 3 seats in each row

Number of seats on left = 2 seats in each row

Total number of seats on right = 90

So, we can find number of rows as:

Number of rows = Total number of seats on right / Number of seats on right in each row

Number of rows = 90/3 = 30 rows

Total number of seats on left = Total number of rows × Number of seats on left in each row

Total number of seats on left = 30 × 2 = 60 seats

Total number of seats on plane = total seats on right + total seats on left

Total number of seats on plane = 90 + 60 = 150 seats
