Question

After adding 45% of a number to the number we get 507.5.What was the number?

Answer 1

Answer: 350

Explanation : Let the number be x.

Acc. to the ques. ,

   x + 45 / 100 * x = 507.5

=> x + 9x / 20  = 507.5

=> ( 20x + 9x ) / 20 = 507.5

=> 29x = 507.5 * 20

=> x = 10150 / 29

=> x = 350

Hence , the number is 350.
