Question

one number is 4 times a first number. A third number is 100 more than the first number. If the sum of the three numbers us 556, find the numbers.

Answer 1

Let x be the first number, 4x is the next and x+100 is the third number. The sum of the three numbers is 556.

 

x+4x+x+100=556

 

6x +100 =556

 

x = 456/6

 

x=76

 

The numbers are 76, 304 and 176
