Question

the amina bibi was increased by 20% and later decreased by 20%, let's work out the total change of percentage of her income.​

Answer 1

Answer: Decrease by 4%

Step-by-step explanation:

Let the original income = 100

An increase of 20% implies her income has become 120% of the current income

So the new income = $\frac{120}{100}$ X 100 = 120

A decrease of 20% implies her income has become 80% of her current income (which is now 120)

So the new income = $\frac{80}{100}$ X 120 = 96

If we compare her new income of 96 with her original income 100

total % change in income = $\frac{96 - 100}{100}$ = - 4%

Hence, her income decreased by 4%
