Answer 1

Answer:

total number of seats=480

Step-by-step explanation:

let,

total numbet of seats= x

then, executive seats are= x/8

business class seats are= x/6

according to the given problem,

x/8+x/6+340=x

=>x-x/8-x/6=340

=>(24x-3x-4x)/24=340

=>17x/24=340

=>17x=340*24

=>17x=8160

=>x=8160/17

=480

therefore,

the total number of seats in the aeroplane=480
