Why we put b as 1?

Let a =100 Now 20% of a i.e. 100 * 20/100 = 20 Rs.
Means 100 Rs of a = 20 Rs of b.
It means 1 Rs of a = 20/100 of b i.e 1/5 Rs.
Now, 20% of 1/5 = 20 * 1/5 = 4 Rs.
Means 100 Rs of a = 20 Rs of b.
It means 1 Rs of a = 20/100 of b i.e 1/5 Rs.
Now, 20% of 1/5 = 20 * 1/5 = 4 Rs.

@Sanjit.
80- 60 % (80),
= 80- 60/100 * 80,
= 80- 48,
= 32.
80- 60 % (80),
= 80- 60/100 * 80,
= 80- 48,
= 32.

20 percentage of a = b.
Then 20 percentage of b = ?
b = 20 percentage of a.
20 percentage of b = 20 percentage of 20 percentage of a.
= 20/100*20/100 of a = 4 percentage of a.
Then 20 percentage of b = ?
b = 20 percentage of a.
20 percentage of b = 20 percentage of 20 percentage of a.
= 20/100*20/100 of a = 4 percentage of a.

(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.
