arsen [322]

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.
