Two number are you less than a third number by 30% and 37% how much percent is the second number less than the first

Answer»

Let the third number is x.
then FIRST number = (100-30)% of x
= 70% of x = 7x/10

Second number is (63x/100)

DIFFERENCE = 7x/10 - 63x/100 = 7x/10

So required PERCENTAGE is, difference is what percent of first number

=> (7x/100 * 10/7x * 100 )% = 10%
