One number is 9 times a first number. A third number is 100 more than the first number. If the sum of the three numbers is 474​, find the numbers.

Answer 1

n = first number

9n = second number

n + 100 = third number

n + 9n + (n + 100) = 474

11n + 100 = 474

n = (474 - 100)/11 = 34

Now get the other 2 numbers and finish from here.
