Question

The sum of three numbers is 89 the second number is 3 times the third the first number is 9 more than the third what are the numbers

Answer 1

According to the given data we have the following:

sum of three numbers=89

second number=3 times the third, so second number=3x

let the third number be equal x

first number=9 more than the third, so first number=x + 9

So, if sum of three numbers=89, then:

x+9 + 3x +x=89

5x=89-9

5x=80

x=80/5

x=16

So, if x=16, then, first number=x + 9=16+9=25

second number=3(16)=48

third number=16
