Download Solution PDFGiven:
Triveni's salary was first decreased by 16% and subsequently increased by 25%.
Formula used:
Net percentage change formula = \( a + b + \dfrac{ab}{100} \)
a = -16 (decrease is taken as negative)
b = 25 (increase is taken as positive)
Calculation:
Net percentage change = -16 + 25 + \(\dfrac{(-16) \times 25}{100}\)
⇒ Net percentage change = 9 + \(\dfrac{-400}{100}\)
⇒ Net percentage change = 9 - 4
⇒ Net percentage change = 5 i.e. 5% Increase.
∴ The correct answer is option (3).
