Question

In an aeroplane 1/8of the seats are in executiv business class 1/6 , are in normal business class, and the rest are in economy class. If there are 340 seats in economy class, what is the total number of seats in the aeroplane?​

Answer 1

Answer:

Total number of seats in the aeroplane = 480

Step-by-step explanation:

Let  the total number of seats be x

Number of seats in economy class = 340

Number of seats in executive class = 1/8x

Number of seats in business class = 1/6x

Therefore number of seats in economy class = x - ( 1/8x + 1/6x )

x - [ (3x+4x)/24 ]

x - 7x/24

17x/24

Now,

Number of seats in economy class = 340 = 17x/24

340*24/17 = x

x = 20 * 24

x = 480
