If A’s height is 10% more than B’s height, by how much

If A’s height is 10% more than B’s height, by how much percent less is B’s height than that of A ?

As we know that If the first value is r % more than the second value, then second value

is		r	× 100		% less than the first value.
		100 + r

Here r = 10%.

∴ Required percentage =	10	× 100 =	100
	110		11

∴ Required percentage = 9	1	%
	11
