Two numbers are respectively 20% and 50% more than the third number. the ratio of these two numbers is ??

Let the third number = xNow, first number = x + 20% of x = x + 20100×x = x + x5 = 6x5second number = x + 50% of x = x + 50100×x = x + x2 = 3x2Ratio of first and second number = first numbersecond number = 6x/53x/2 = 45 = 4 : 5

let the third no. be x

Then two numbers =

1st no. =x + 20x/100 = 120x/100

2nd no. = x + 50x/100 = 150x/100

1st no. : 2nd no.

= 120x/100 : 150x/100

= 120x/100 / 150x/100

= 120x/100 × 100/150x

= 4/5

= 4:5

Let the third no. be 10

Then First no. is 10 + 20/100 * 10 = 12

Second no. is 10 + 50/100 * 10 = 15

First and the second no. are in the ratio of 12:15 or 4:5
