The difference between the value of a number increased by 25% and the value of the original number decreased by 30% is 22. What is the original number?
Let the number be N.
If the number increases by 25%, it becomes 1.25N, and if it decreases by 30%, then it becomes 0.7N. The difference between them is given as 22,
1.25 N - 0.7 N = 22
=> N = 22/0.55 = 40
