Problema Solution

If a number is 20% more than the other, how much percent is the second number less than the first?

Answer provided by our tutors

let 'x' and 'y' represent the numbers


x is 20% more than y means:


x = 1.20*y


then for y we have:


y = (1/1.20)x


y = 0.83*x


meaning y is 83% of x or it is 100 - 83 = 17% less than x.
