Question

One number is 66 times a first number. A third number is 100 more than the first number. If the sum of the three numbers is 732732?, find the numbers

Answer 1

The first number can be represented by x. Using x to represent the first number it follows that the second number is 66x, and the third number is x+100. Adding these numbers together equals 732732. So add them and set them equal to 732732.

 

x+66x+x+100=732732

 

Now combine like terms and solve for x.

 

68x+100=732732

68x=732732-100

68x=732632

x=732632/68

x=10774

So the first number is

x=10774

the second is

66(10774)=711084

and the third is

10774+100=10874.
