Question

A number is increased by 25% and decreased by 20%.The result is what percent of the original number?​

Answer 1

Answer:

5% more

Step-by-step explanation:

Let the number be 'x'

When the number is increased by 25%, the new number is x + 25% of x

= x + (25/100)x

= x + 0.25x

= 1.25 x

When this number is decreased by 20%, the new number is 1.25 x - 20% of x

= 1.25x - (20/100)x

= 1.25x - 0.2 x

= 1.05 x

Difference between original number and new number = 1.05x - x

= 0.05 x

= (100 * 0.05) % of x

= 5% of x

So, the new number is 5% more than the original number.
