Question

A positive number is 7 times another number. If 25 is added to both the numbers, then one of the new numbers becomes twice the other new number. What are the numbers

Answer 1

Answer:

Let 1st number be x

Then second number is 7x

If we add 25 to both numbers,

New numbers are,

x + 25 and 7x + 25

Equation is,

2 ( x + 25) = 7x + 25

2x + 50 = 7x + 25

2x - 7x = 25 - 50

-5x = - 25

So x = 25/5 = 5

If first number is 5, then second number is 35
