Answer:
Total number of seats on plane is 150 seats.
Step-by-step explanation:
Number of seats on left side = 2 in each row
Number of seats on right side = 3 in each row
Total number of seats on right side = 90
Number of rows = total number of seats on right side/ number of seats on right in each row
Number of rows = 90 / 3 = 30 rows
So, total number of seats on left side = 30 * 2 = 60 seats
Total number of seats = total seats on right side + total seats on left side
Total number of seat = 90+ 60 = 150 seats
Hence total number of seats on plane is 150 seats.
