The number was reduced by 20%. By what percentage you need to increase the resulting number so that it remains the same. Example 20.

The initial number is 20. This figure is 100%. Let’s reduce it by 20%:

100% – 20;

20% – H.

Where from:

X = 20 x 20/100;

X = 4;

20 – 4 = 16.

So the new number is 16. Now it is 100%. Now, how many percent do you need to increase it to get back 20:

100% – 16;

Y – 4.

Where from:

Y = 4 x 100/16;

Y = 25.

Answer: in order for the number to become the same, you need to increase the new number by 25%.
