Question

600 or 600 decreased by 20% and then increased by 20% of the result? Which amount is larger and by how much

Answer 1

Answer:

The initial value of 600 is larger and larger by 24.

Step-by-step explanation:

First of all a 20% decreased of 600.

So, the new value will be $600(1 - \frac{20}{100}) = 600 \times 0.8 = 480$.

Now, then it is increased by 20% i.e. 480 will be increased by 20%.

So, the new value will be $480(1 + \frac{20}{100}) = 480 \times 1.2 = 576$.

Therefore, the initial value of 600 is larger and larger by (600 - 576) = 24. (Answer)
