Q:
Two numbers are 20% and 30% less than the third number . How much percent is the second number less than first?
Answer
Let the third number be 100.
Then, the first number = 100 - 20 = 80 and second number = 100 - 30 = 70.
Difference between the first and second number = 80-70 = 10
Required percentage = % = 100/8 = 12.5%
