In traditional Indian culture how much dowry did the parents of the bride offer the parents of the groom?

I realize this is a dated custom and has likely fallen out of fashion. I have checked the Indian Dowry Law and see that this practice was banned in 1961. However, I am looking for a number that would apply to a traditional old school, arranged marriage. If the bride is “older”, let’s say late 20’s, how much did her family give to the groom’s family?
I am guessing there are many rules and percentages that affect the amount such as: parents’ income, bride’s income, groom’s income, etc. Let’s also assume the parents are well off professionals.
I am just looking for a rule of thumb.

Thanks for your help.
