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 |

They said comparing both 1st & 2nd third parts is less and it is Percentage. So For third part take it as 100%.
Then for 1st part 120% & 2nd part 150%.
Then 120% : 150% : 100%. Then the answers is 4:5.
Then for 1st part 120% & 2nd part 150%.
Then 120% : 150% : 100%. Then the answers is 4:5.

Confused guys. Please read the question carefully.
Its first and 2nd number is 20% and 50 % more than the third number.
Obviously that means that the third number should be 100% or you can take it as 100.

Let A, B, C are three numbers.
A is 20% more than C.
So A become:
A= C+20%of C = C+0.2C = 1.2C.
B become:
B= C+50%of(C)= C+0.5C = 1.5C.
And ratio between A/B is:
1.2C/1.5C = 4/5.
Hence answer is:4/5.
A is 20% more than C.
So A become:
A= C+20%of C = C+0.2C = 1.2C.
B become:
B= C+50%of(C)= C+0.5C = 1.5C.
And ratio between A/B is:
1.2C/1.5C = 4/5.
Hence answer is:4/5.

How to solve if we have been asked the 2nd number is greater than 100.
Like, Two numbers are respectively 40% and 110% more than a third number. The ratio of the two numbers is:?
Anyone, please help me.

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.

We know there are 3 numbers.
Think.,
1st one X.
2nd one Y.
3rd one Z.
Then assume that Z's value a.
Now X=a+20%.
Y=a+50%.
Put a=10.
Now we get X=12; Y=15.
So the ratio of X and Y is 4:5.

@Sujaathasree.
If the percentage increases or mentioned directly we can take it as 100+20% since the percentage increases directly to 100 and if loss or decrease by 20% then we should do 100-20%.

Very simple method is:
Let assume that 3th number is = 100.
Then,
a/c to ques. A = 120.
B = 150.
Ratio of number A/B = 120/150.
= 4/5.
A:B = 4:5 (ANS. C).

Suppose the 3rd number is x.
Then first no. will be more than 20% of third no.
So first no.=x+20x/100=6x/5.
second n0.=x+50x/100=3x/2.
so, the ratio of first and second no.=6x/5*2/3x=4:5.
Then first no. will be more than 20% of third no.
So first no.=x+20x/100=6x/5.
second n0.=x+50x/100=3x/2.
so, the ratio of first and second no.=6x/5*2/3x=4:5.

Let the third number be x = 100.
The first number is 20% more than third number so 100+20% = 120.
The second number is 50% more than third number so 100+50% = 150.
= 120:150 = 4:5.
The first number is 20% more than third number so 100+20% = 120.
The second number is 50% more than third number so 100+50% = 150.
= 120:150 = 4:5.
