Question

A number is increased by 200%. The result is then decreased by 100%. What is the final answer?

Answer 1

2n (The original number times two)

Explanation:

200% is just another way of saying the number (n) times 2, so n + 200% is the same as n + 2n = 3n

So too 100% is just n so 3n - n = 2n
