Answer:

30

Step-by-step explanation:

We need to find the number, which, when increased by 130% equals to 69

It can be written as following equation if we call the number x:

  • x + 130% of x = 69
  • x + x*1.3 = 69    ========= 130% of x equals to 1.3 x
  • x (1+1.3) = 69
  • 2.3x = 69
  • x = 69/2.3
  • x = 30

So the answer is 30
