OPTION:C.
Let the third number be x.
20%x = 0.2x (and the number is more than a third of the number that is x) then,
=>x+0.2x = 1.2x,
50%x = 0.5x,
=>x+0.5x = 1.5x.
12:15=>4:5

Here third nbr 100 say.
20%,50%is more than 100 respectively.
then;
120 %, 150%, 100%.
120 : 150 : 100.
120 : 150.
4 : 5.
20%,50%is more than 100 respectively.
then;
120 %, 150%, 100%.
120 : 150 : 100.
120 : 150.
4 : 5.

Let x first number is 100 , 20% is more i.e; 120.
Let y second number is 100, 50% is more i.e; 150.
So, 120 : 150 is 4 : 5.
Let y second number is 100, 50% is more i.e; 150.
So, 120 : 150 is 4 : 5.

Let A = 1.2 X.
Let B = 1.5 X.
A/B = 1.2X/1.5X,
A/B = 4/5,
A:B = 4:5.
Let B = 1.5 X.
A/B = 1.2X/1.5X,
A/B = 4/5,
A:B = 4:5.

Let, the third number is 100.
now the first is 20% more than 3rd number = 120.
and the second number is 50% more than the 3rd number = 150.
Then, 1 num : 2 num.
120 : 150.
So, the answer is 4:5.
now the first is 20% more than 3rd number = 120.
and the second number is 50% more than the 3rd number = 150.
Then, 1 num : 2 num.
120 : 150.
So, the answer is 4:5.
