Reasons for an arrange marriage for a girl (In India) in early/mid/late 30’s

This is my idea after doing an unofficial research between some friends and acquaintances. It may or may not be the real reason of the world, but this is what I understood. 
Also acquaintances from various income groups were questioned, and this was overall the result!

NOTE: 

This is not an official research, but done for fun sake. So please take it lightly!

If you don’t like the research, too bad! Go do your own research!
