The first number is 40% less than the second. How much more is the second number?

It is known that the first number is 40% less than the second, that is, the second number is 100%, and the second will be 60%;

Let’s determine how much more the second number will be from the first:

We use the proportion method:

We take the first number 60% as 100%;

The second number being known as 100% – relative to 60% of the first number is unknown, let us denote – “x”;

60 – 100%;

100 – x%;

60 x x = 100 x 100;

60x = 10,000;

x = 10000/60 = 2000/12 = 500/3 = 166.2/3 ~ 170;

170 – 100 = 70%;

Answer: the second number is 70% more than the first.
