@All.
I have another method.
we can take a=100.
20% of a = b;
20% of 100 = 20; it means b=20%
20% of 20 = 4.

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.

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

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

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%.

Let's 20% is 1/5.
1/5 * 20 = 4.
1/5 * 20 = 4.

Take 100% as complete;
Now solve the first part;
20% of A means 20% of 100,
Then B is already the same as A means B is also 20%.
According to the question;
B = 20%.
20% of 20 is 4.

Given :0
20% of a= b
1/5 a = b
b = a/5 ..
To find : b% of 20 =?
(a/5)% of 20 which can be written as 20% of a/5 = 4% of a.
20% of a= b
1/5 a = b
b = a/5 ..
To find : b% of 20 =?
(a/5)% of 20 which can be written as 20% of a/5 = 4% of a.
