| 100 | 5 |
| Second number = 150% of x = | 150x | = | 3x |
| 100 | 2 |

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

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 c 100.
A = 120.
B = 150.
So the ratio of A to B.
120/150.
4 : 5.
A = 120.
B = 150.
So the ratio of A to B.
120/150.
4 : 5.
