Question

4. The sum of two numbers is 100. If one is four times the another, find the numbers
​

Answer 1

Let the numbers be x and 4x. So, according to the question,

x + 4x = 100

=> 5x = 100

=> x = 100/5

=> x = 20

So, the number are,

x = 20

and

4x = 4×20 = 80

So, the two numbers are 20 and 80.
