If 20% of a = b, then b% of 20 is the same as: Choices
A) 4% of a	B) 5% of a	C) 6% of a	D) 3% of a	E) 2% of a
Here, 20% of a=b i.e.,(20/100)a=b   then, b% 20 i.e.,(b/100)x20---I   then sub b=(20/100)a in I   we get,   =(20/100)a x (1/100) * 20   =(20/100)a x (20/100)   =(400/10000)a   =(4/100)a   = 4% of a   4% of aNSWER :4% of a

If 20% of a = b, then b% of 20 is the same as:
