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.

I took x:x+20:x+50
then i assumed x+(x+20)+(x+50)=100
3x+70=100
x=10
hence the ration is 30/60
1/2
where did i go wrong?
then i assumed x+(x+20)+(x+50)=100
3x+70=100
x=10
hence the ration is 30/60
1/2
where did i go wrong?

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.

Suppose a number,
100____120.
100 ___150.
Hence the numbers are increasing by 20 and 50%
120 : 150.
12 : 15.
4 : 5.
100____120.
100 ___150.
Hence the numbers are increasing by 20 and 50%
120 : 150.
12 : 15.
4 : 5.

Percent = cent means 100 okey then.
20% n 50% just add them a 100.
120 n 150.
120 : 150 simplify.
4:5 Answer simple way.

Assume the third number as X,
so x+20/100 // x+50/100,
120x/100 // 150x/100,
6/5 : 3/2 => 6 * 2 : 5 * 3 => 4 : 5.
so x+20/100 // x+50/100,
120x/100 // 150x/100,
6/5 : 3/2 => 6 * 2 : 5 * 3 => 4 : 5.

Let the third number be 100.
1st number is 120, and the second number 150.
Then the ratio of 120 and 150 will be 4:5.

20% -----> 4*5=20%
50% ------> 5*10=50%
Ratio is ---- (c) 4 : 5.
So, Option (C) is the Right answer.
50% ------> 5*10=50%
Ratio is ---- (c) 4 : 5.
So, Option (C) is the Right answer.

Let the third no. Be = 100.
Then add 100 in 20% and 50%.
It will be 120 and 150.
=120 : 150,
= 12 : 15,
= 4 : 5.
Then add 100 in 20% and 50%.
It will be 120 and 150.
=120 : 150,
= 12 : 15,
= 4 : 5.
