Question

If two numbers are 30% and 50% of a certain number,then first number is what% of second number?

Answer 1

First number is 60% of second number.

Step-by-step explanation:

Let third number be  = x

Then first number

30% of x = 30x/100

Second number

50% of x  =  50x/100

Percent of first number of second number :

= [ 30x/100 ÷ 50x/100] x 100

= 30/50 x 100

= 0.6 x 100

= 60%

Thus first number is 60% of second number.
