Question
A number is first increased by 60%, then increased by 20%
and then decreased by 40%. If the resultant number is 403.2, then find the original number.Solution
ATQ,
Let the original number be '100x'.
ATQ;
100x × 1.6 × 1.2 × 0.6 = 403.2
Or, 115.2x = 403.2
So, x = 3.5
So, original number = 3.5 × 100 = 350
