Question

The first aircraft has 89 more seats than the second aircraft. The third aircraft has 17 fewer seats than the second aircraft. If their total number of seats is 372​, find the number of seats for each aircraft.

Answer 1

100

189

83

Explanation:

Firstly, we can see that there are three aircrafts. Let the number of aircrafts in the second aircraft be x.

Then the first has 89 more seats meaning it has a total seats of x + 89

The third has 17 fewer seats meaning x - 17

Now we are expected to find the number of seats on each of the aircraft officials.

We add all and then sum to the total 372.

This means

x + x + 89 + x - 17 = 372

3x + 72 = 372

3x = 300

x = 300/3 = 100

The aircrafts thus have 100 seats, 189 and 83 seats in no particular order
