Q39
ArithmeticPercentage, Profit & Loss
The salary of a man is decreased by 50% and then in the next year it is increased by 60%, then the resultant increment of his salary is:
- a.10%
- b.15%
- c.−20%
- d.−25%
Answer: (C) −20%
Take the salary as 100: after a 50% cut it is 50, and a 60% rise makes it 80. The net change is 80 − 100 = −20%. Simply adding −50 and +60 gives the wrong +10%.
