Answer 2

Concept Introduction:

A percentage is a figure or ratio stated as a part of 100 in mathematics. Although the abbreviations "pct," "pct," and occasionally "pc" are also used, the percent sign, " percent ", is frequently used to signify it. A % is a number without dimensions and without a standard measurement.

Solution:

Given, Two numbers are $20 %$% and $30$% less than the third number.

We have to find the percentage in the second number less than the first.

Let the 3rd number be, $100$

The 1st and 2nd number are $80$ & $70$ respectively

Difference between the first and second number = $80 - 70 = 10$

Therefore required percentage = $10 / 80$ ×$100 = 12.5$

Final Answer:

The final answer is $12.5$
