Question

13. Two numbers are respectively 20% and 50% more
than a third number. The ratio of the two numbers
is:​

Answer 1

Answer:

Let the third number be x.

100+20

100 represent x

The first number is 20% more than x

So 120 of x comes

Then, first number = 120% of x =120x/100 = 6x/5    

Second number =150% of x = 150x/100 = 3x/2  

Ratio of first two numbers = 6x/5 : 3x/2 = 12x : 15x = 4 : 5
