b = 1/5 a.
a : b = 1 : 5.
5-1 = 4% of a.
a : b = 1 : 5.
5-1 = 4% of a.

If a is 100 then b=20 which is 1/5.
Hence if b=20 then 1/5 of 20 is 4.
Hence if b=20 then 1/5 of 20 is 4.

Hi,
20/100a * 1/100 * 20 ,
400a/10,000,
4/100a%.
Now,
4/100 *100 = 4%.
20/100a * 1/100 * 20 ,
400a/10,000,
4/100a%.
Now,
4/100 *100 = 4%.

A = 100 then 20 of B%.
Then (A-B).
So, 100 - 20 = 80.
80/20,
= 4%.
Then (A-B).
So, 100 - 20 = 80.
80/20,
= 4%.

(5/3)X - P% of (5/3)X = (3/5)X.
After solving this equation for the value of P, we will be getting the percentage error.

Let a=100.
20% of a=20,
then b=20,
as per the question b% of 20 is?
So 20% of 20 is 4.

Let's say a = 100.
0.2 * 100 = 20 which is B,
So,
0.2 * 20 = 4 which is equal to 0.04 * 100= 4.
0.2 * 100 = 20 which is B,
So,
0.2 * 20 = 4 which is equal to 0.04 * 100= 4.

A = 100,
B = 20.
20% of B = 2 * 2 = 4.
B = 20.
20% of B = 2 * 2 = 4.
