Hi Ankit, yes there is a small error. Actually, we need to divide by 80 and multiply by 50. We are dividing by 80 as we have assumed linear distribution of age factor (every age year would have equal number of people and 80 is the life expectancy that we are taking). Further we multiplied with 50 to get the number of people within the selected age group. Hope this helps
At 2.07 why did you multiply by 80 to calculate the marriageable people in urban population. shouldn't the multiplication be by 50 here??? further why did you divide the 5 crore by (28 - 18) again??
Yes, there is an erratum...so basically for eligible urban population u need to divide by 80 and multiply by 50 For 2 nd question, as we have assumed that ppl within selected age group will marry only once thus, we have divided the eligible no of ppl by the selected range
As we have assumed the population to be linearly divided , thus, we are dividing the 80 crore population by 80 to get number of people of each year and then we are multiplying it with the age bracket assumed for rural area...hope this answers your question
Basically, the assumption over there is that generally speaking that people belonging in marriageable group would not marry within the same year. So we have divided the 'no. of girls' to distribute the weddings across years and we have used age bracket to align with our assumption that it is age bracket in which the wedding would take place . Hope this helps.
@@akshaychauhan2757 Basically we are equally spreading the people who can marry across the marriageable bracket as all the eligible people can not simply marry in a single year.
Please explain the last step
When we are dividing agre group by 5
Why did we divide by age range in the end?
Because each person falling into that age group will marry only once.
how did come up with the formula for people of marriageable age?
Sir can you prepare a video on how we can estimate the no. of delivery boys required for any particular outlet of Domino's.
Good example of guesstimate
Nice one sir.
How the heck that formula came
@2.38 you have calculated {(35-20)/50}*80 as 9.3 crore?? Can you please explain

He is assuming that the age range mentioned includes 80% of rural/urban population.
@@Miss_messyhead so it's an assumption that 80% between that age range gets married?
Can you please explain why did you divide by 80 in the rural population section?

Thank you so much, especially for replying ASAP 😁
@@cfe1301 didn't get... Any other method..
@@cfe1301 no
Can you please explain why you divided no of girls by marriage bracket to arrive at no of weddings?
