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.
