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 |
![]() |

Let c 100.
A = 120.

So the ratio of A to B.
120/150.
4 : 5.
A = 120.
B = 150.
So the ratio of A to B.
120/150.

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.
1st number is 120, and the second number 150.

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.

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 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.

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.

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

Third number = x
First number = 20x/100
Second number = 50x/100
Assuming x = 10.
Put the value'
= (20*10/100) + 10 = 12,
= (50*10/100) + 10 = 15,
= 12:15.
= 4:5.
First number = 20x/100
Second number = 50x/100
