Question
A number is first increased by 200%, then increased by 10%
and then decreased by 90%. If the resultant number is 108, then find the original number.Solution
ATQ,
Let the original number be '100x'.
ATQ;
100x × 3 × 1.1 × 0.1 = 108
Or, 33x = 108
So, x = 3.27
So, original number = 3.27 × 100 = 327
