Download Solution PDFGiven:
Increment in income for the first month = 30%
Decrement in income for the second month = 30%
Formula used:
Effective percentage change in salary = Inc. - dec. - (inc × dec)/100
Where, Inc = increment%; dec = decrement%
Calculation:
Effective percentage change in salary = Inc. - dec. - (inc × dec)/100
⇒ 30 - 30 - (30 × 30)/100
⇒ 0 - 9 = - 9%
Note: (- Ve) sign denotes the decrement in salary
∴ The correct option is 4.
