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 |

Suppose the 3rd no is X.
so 1st no will be X*1.2.
&2nd no will be X*1.5.
so the ratio is 1.2:1.5,
Hence 4:5
so 1st no will be X*1.2.
&2nd no will be X*1.5.
so the ratio is 1.2:1.5,
Hence 4:5

Take 10 and 20% more than 10 is 12 and 50% more than 10 is 15 so the ratio is 12:15 which is nothing but 4:5 .

@All.
Here,
First and second numbers 20% and 50% more that means 120:150 simply this we will get 4:5.

Let number = x, y, z.
Then, x = 20% of z + z = 6z/5.
y = 50% of z + z = 3z/2.
Ratio is x/y = 4/5.
Then, x = 20% of z + z = 6z/5.
y = 50% of z + z = 3z/2.
Ratio is x/y = 4/5.

How do you get 120/100? And how do you get the answer 6 over 5? I'm confused. Please clarify me.

a : b:
20%:50%
20/100 = 2/5
50/100 = 1/2
a:b :: c:d.
2:5 :: 1:2.
= answer 5:4 or 5/4.

Let the third number will taken as 100.
= 120/100 = 150/100 = 12 = 15.
= 4 = 5.
= 120/100 = 150/100 = 12 = 15.
= 4 = 5.
