A person's salary was decreased by 50% and subsequently increased by 50% and then again increased by 100%. How much percentage does he lose or gain?
Answer & explanation
Correct answer: option 2
Let the salary = 100
ATQ = 100 × \(\frac{1}{2}\) × \(\frac{3}{2}\) × \(\frac{2}{1}\) = 150
Gain = 150 - 100 = 50%
