- If 20% of a = b, then b% of 20 is the same as:
Question 1:
If 20% of a = b, then b% of 20 is the same as: A. 4% of a
Feedback 20% of a = b => (20/100)a = b
Therefore b% of 20 =[(b/100) X 20 ] = [ (20/100)a X (1/100) X 20 ] = (4/100)a = 4% of a.
Therefore b% of 20 =[(b/100) X 20 ] = [ (20/100)a X (1/100) X 20 ] = (4/100)a = 4% of a.
B. 5% of a
C. 20% of a
D. None of these
