(20/100)*a equals b.
a equals b*100/20.
a equals 5 b.
b equals a/5.
Implies b equals 20 percentage of a.
a equals b*100/20.
a equals 5 b.
b equals a/5.
Implies b equals 20 percentage of a.

If a=100 then 20% of a is b = 20.
20% of b =4.
( b% of 20 is the same as 20% of b).
4 out of 100 (4%).
20% of b =4.
( b% of 20 is the same as 20% of b).
4 out of 100 (4%).

Suppose a=100.
then b=20%a,
b=20/100*100 (a=100),
b=20,
Means if b=20.
20% of 20=20/100*20.
= 4%.
then b=20%a,
b=20/100*100 (a=100),
b=20,
Means if b=20.
20% of 20=20/100*20.
= 4%.

Lets say A = 100, and B is 20% of A, So B = 20.
Now, what 20% of B.( we need 20% from 20) i.e 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.

@Habiba simple step :
60-15 : 45.
At present he bought it at 15 So,
It is (45/15)*100: 300.
60-15 : 45.
At present he bought it at 15 So,
It is (45/15)*100: 300.

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.

20% of a = b,
20/100 of a = b,
0.2 of a =b,
b% of 20.
0.2/100a * 20,
2/10 * 20a,
4%.
20/100 of a = b,
0.2 of a =b,
b% of 20.
0.2/100a * 20,
2/10 * 20a,
4%.

20% of a = b.
Let a = 100.
= 20/100*100 = 20.
b = 20.
= 20/100*20 = 4.
4% of a.
Let a = 100.
= 20/100*100 = 20.
b = 20.
= 20/100*20 = 4.
4% of a.

Putting the value of b in b of 20% = 20% of a of 20% = 4/100 x a= 4% of a.
