Two numbers are respectively 20% and 50% more than a third number. The ratio of the two numbers is:
Answer: Option
Explanation:
Let the third number be x.
| Then, first number = 120% of x = | 120x | = | 6x |
| 100 | 5 |
| Second number = 150% of x = | 150x | = | 3x |
| 100 | 2 |
 Ratio of first two numbers = |
 |
6x | : | 3x |  |
= 12x : 15x = 4 : 5. |
| 5 | 2 |

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.

Let the third number be denoted as x.
The first number is 20% more than x.
Therefore, the first number is: x+0.2x = 1.2x.
The second number is 50% more than x.
Therefore, the second number is x+0.5x = 1.5x.
We need to find the ratio of the first to the second number: 1.2x/1.5x.
The x terms cancel out, simplifying the ratio into 4/5.
So, the Answer is 4/5.
The first number is 20% more than x.
Therefore, the first number is: x+0.2x = 1.2x.
The second number is 50% more than x.
Therefore, the second number is x+0.5x = 1.5x.
We need to find the ratio of the first to the second number: 1.2x/1.5x.
The x terms cancel out, simplifying the ratio into 4/5.
So, the Answer is 4/5.

Consider third number as X.
The question say's that 1st number is 20% more than the third number means a = 20%X + X.
Similarly,
Second number = b = 50%X + X,
a/b = 0.2X + X/0.5X + X,
= X(0.2 + 1)/X(0.5 + 1),
= 1.2/1.5.
= 4/5.
