Question

The sum of three numbers is 117 . the third number is 3 times the second. the first number is 8 less than the second. what are the numbers?

Answer 1

Let the second number be x.

First number = x - 8

Third number = 3x

Sum of the numbers = 117

x - 8 + x + 3x = 117

5x = 125

x = 25

Thus,

The first number is 17. The second number is 25. The third number is 75.

Answer 2

The numbers are :17, 25 and 75

Explanation:

Let the second number of x.

The third number is 3 times the second = 3x

The first number is 8 less than the second = x-8

the sum of three number are = 117

`(x-8)+x+3x=117`

`5x=125`

`x=(125)/(5)=25`

First number = x-8 = 25 - 8 =17

Second number = x = 25

Third number = 3x = 3 × 25 =75
