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


 


\inline \therefore Required percentage = 1080 x 100% = 100/8 = 12.5%
