| 100 | 5 |
| Second number = 150% of x = | 150x | = | 3x |
| 100 | 2 |
 Ratio of first two numbers = |

20%= 120.
50% = 150.
120:150 = 120/150 = 4:5.
50% = 150.
120:150 = 120/150 = 4:5.

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.

ATP,
1st no., Is 20% more than 3rd no.
Let 3rd no., be x;
Then, 1st no.,=(20/100)*x+x.
2nd no.,=(50/100)*x+x.
Finally,
1st = 120x/100.
2nd = 150x/100.
3rd = x.
Ratio required = 120x/100:150x/100.
= 4:5.
1st no., Is 20% more than 3rd no.

3rd = x.
Ratio required = 120x/100:150x/100.
= 4:5.
