Q1) Number of Hajmola eaten per day ?
Ans) India's population is 120 Crores
People below poverty line can be safely discarded (30%)
Remaining = 120 * (1 - 0.30) = 84 Crores (Approximated to 80 Crores)
We assume Hajmola is eaten in age groups (5-15) and (15 - 25) and other form an immaterial part of the customer segment
Q2) Number of cosco balls in a plane
Ans) Assuming a empty plane (no passengers) but intact with seats and machinery.
ques - Number of rows - 40
ques - which plane make - Boing 747 (6 seats in a row)
Assumption - Seat length - 0.5 mt Distance between seats - 0.5mt
Length of plane = [3mt cabin + (0.5+0.5 mt) * 40 + 2mt (tail space) ] = 45 mt
Width of plane = [6 seats of 0.5 mt + 0.5 mt aisle] = 3.5 mt (diameter)
radius = (3.5)/2mt
cylindrical shape volume = pi r*r*h = pi * (3.5/2) (3.5/2) 45mt
adjustment = volume of 4 washrooms + volume of luggage space - volume occupied in seats
radius of cosco ball = 3 cm
Volume of cosco ball = 4/3 pi r*r*r = 4/3 pi (3/100) (3/100) (3/100)
Gaps are left between balls. So we assume total volume taken is 10 % higher than cosco balls actual volume
Number of cosco balls = [pi * (3.5/2) (3.5/2) 45mt + adjustment] / [4/3 pi (3/100) (3/100) (3/100) (1.10)]
Q) Helmets sold every year in India
Ans) Step 1 - How many bikes are there in India
Helmets are required for people travelling on bikes. We can remove the population in bottom of pyramid
Lets say 60% of people are above poverty line and can afford a bike. 120Cr * 0.6 = 72 ~ 70 Cr people
We can remove below 18 years (30%) and above 60year (10%) from the consideration set
Left consideration set = 70Cr * 60% = 42 Crore (Surds dont need to wear helmet) ~ 40 Cr
= 3.7 Cr
For every bike lets say there are some pillion riders as well. Avg helmets per bike = 1.2
Total helmets - 3.7 Cr * 1.2 = 4.5Cr in India
Lets say people buy a new helmet every 3 years. We have 1.5Cr helmets getting sold every year.

We assume Hajmola is eaten in age groups (5-15) and (15 - 25) and other form an immaterial part of the customer segment
Fact: approx 2.5 Cr Hajmola tablets are eaten per day
