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%.

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.

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%.

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

What is b% of 20,
20/100*20 = 4%.
a=b = 20%
What is b% of 20,
20/100*20 = 4%.

20% a = b
when b is 20.
a = (20/100)*20,
a = 4.
when b is 20.
a = (20/100)*20,
a = 4.
