Assuming total Population to be 135 Crores and No.of marriages = New + remmariages(post divorce and such sort) Assumptions for New marriages: Age group of 21-27 yrs looks to get married and % of total population of this age group being 15% and out of this age group approx 15% people gets married So new marriages= 135*0.15*0.15*0.5(a marriage is consitute of male and female)=1.4 Crore Remarriages: % of people in 30-55 yrs being 25% and % divorce rate being 1% Remarriages= 135*0.25*0.01*0.5=.17 Crores So total marriages= 1.4+.17 ~ 1.6 Crore marriages If any mistake, please clarify. Thanks
@chhavihere2 жыл бұрын
Your initial part is right, after that it is confusing. Why will only 15% people get married out of marriageable age? Also we are asking yearly marriage - not everyone gets married in 1 year.

@@chhavihere Hey I did it like this can you see if this is correct or not? The population of India is approximately 1.4 billion out of these 30% a living in urban areas and 70% are living in rural areas in rural areas the chances of finding an AC is relatively low so we will assume that people in rural areas do not have an AC there for 1.4 * 30% gives us a value of approximately 400 million out of these 400 million people we will as you that 20% of the population is living in the below poverty line or lower income segment Therefore 400 * .8 gives us roughly 300 million peopleNow since in the India the average family consist of three people therefore the total number of families in India is 300 / 3 which is equal to 100 million household Households can be divided into Lower class middle class and higher class we will assume that Lower class percentage is 40% upper middle class percentage is 30% and the higher class is 30% This means that lower class people are 40 million apartmeter class people are 30 million and the rich are also 30 million the lower class will only have one AC for household whereas the upper middle class will have two AC and rich people will have four AC The total number of ACS will become 40 x 1 + 30 * 2 + 30 * 4= Which gives us 200 million ACSince AC is are quite expensive so they are replaced every 10 years therefore the number of AC is sold per year would be 200 million / 10 which gives us 20 million

@Chhavi Gupta In my Interview, I was cross questioned a lot when I segmented further on the basis of income group like 1:2:4:3 of Upper: Upper Middle: Middle: Lower, I couldn't justify why I took that ratio as a fact, Could you justify that if I'm asked the same in another interview basically how to justify the ratios that you mentioned in the fact sheet be it Rural : Urban= 7:3 or Poor:Middle:Rich etc. ? Thanks for consideration.
@chhavihere2 жыл бұрын
Generally you won't need to justify it. You can say like, BPL in India is 20% - so that's a fact. Some things are facts and you've to sound confident in interview to say, this is the approximate ratio for Indian population.

Please let me know if this approach is correct: I took the population at 1300M Then I took half of it to count a marriage once so 650M Then I took the age bracket of 16-55 which has 60% of the population(also including outliers who get married before 18 and after 50) Giving 390M Then I considered that an average person gets married once in the span of 40 years hence 2.5% of 390M which is 9.5M Close to the actual answer of about 10M

To estimate the increase in market of ACs at the end of 10 years, what if we divide population age-wise , suppose say today 200mn people are in the age group 10-20 years. The same will be in the age group 20-30 years after 10 years and a fraction among them will be able to buy AC and that's what is the reason behind market growth right? And so we can estimate growth using this number, can we? Please guide

i tried the no. of weddings per year in india approach: population: 140 crore say 5% wont marry, rounding it off to 10 crores with 130 crores left: i divide into 3 categories as [0-20, 20-30(marriageable), 30-80] considering the declining average age of humans(upper limit as 80 years) i take 15% for the 20-30 range, 20% 0-20, 60% for 30-80 Is this logic right ? i.e. approx. 20 cr people in 20-30 range out of these let average age of marriage be 25 years. so lets say all will marriages will be at 25 only. So can i divide these 20 cr by 10 because i'm selecting only one year out of 10 years(20-30) ? if i do this i get 2 cr people now with male to female ratio as 5:4, we get females and thus weddings as 0.88 crore or 88,00,000. is this acceptable ? ans. as per internet is 1,00,00,000

Doesn't this approach take 1 AC per person of population? It should be divided by average family size, right ?
@chhavihere4 жыл бұрын
Have done it for number of households only
@arujbudhraja4 жыл бұрын
It's actually easy. I got the ACs to be around 36 lakhs (market = 45 lakhs). Regarding the weddings in India per year:- -> Using Top Down approach: 135 cr population. Sex ratio in India is 108 male to 100 females. Or 52% male and 48% female. 48% of 135 cr = 64.8 cr. (65 cr). Now youth population of India is 1/5th. 20% of 65 cr = 13 cr. Now these are females from age of say 15-25. If we assume one gets married at 25+ age, we reach answer / 10 (per age). So 13 cr / 10 = 1.3 cr weddings in India per year. (Actual answer = 10 million / 1 cr.) I hope this qualifies as an answer.
@chhavihere4 жыл бұрын
It does. Good attempt :) Only 1 advise. Do not take 52%-48% Remember you can't generally use a calculator in an interview so this will be a very very tough mental math problem.
@adityapattanayakvlogs4 жыл бұрын
I have a doubt ; if we consider the females of age 25+ ; then we must take the 52 cr population NAA as you've considered all the youth population (13 Cr) to be of age 15-25 . So they're not eligible for marriage . So we should consider the other part of the population in our problem . Kindly clarify a bit on this .
