Updated: Nov 18, 2022

Mobiprep has created step by step solution to estimation questions for all product management and consulting interview questions to help you with the mastering placement interviews. So letâ€™s get started with the estimation questions.

Our team has curated a list of the most important product management frameworks asked in interviews such as Google, Deloitte, McKinsey, Microsoft, EY, ZS and many more. The frameworks are created from the best practices adopted by previous year candidates.

In this estimation question we have analysed the market size of the number of dogs in Delhi. Check out the step-by-step answer created by Mobiprep experts.

### Estimation Question Step-1: Segmentation

Population of Delhi = 1.5 Crores or 150 Lac

Avg. family size = 4-5

Total Families = 30 to 37.5 lacs

Assuming 35 Lacs Families

Therefore, No. of families that can have dogs:

= 0.7 lac + 1.225 lac + 0.7 lac

= 2.625 lacs

Now some people have more than one dog, let avg. number of dogs per family be 1:1 , dogs/family.

No. of Pet dogs = 2.625 * 1.1 lacs

= 2.625 + 0.2625

= 2.8875 Lacs

~ 2.9 Lacs Pet dogs ------(1)

Stray Dogs = Average population density * area of Delhi

Area of Delhi estimated = 1800 sq.km

Avg. Population per sq.km = 20 (by analyzing the area around you)

Therefore the number of stray dogs = 36,000 dogs -----(2)

Police Dogs:

70 Constituencies in Delhi

Let there be 2 police station per constituency and 10 police booth per constituency. At an Avg. let there be 5 dogs and 2 dogs respectively at a police station and a police booth.

Also, since not every booth has a dog , let 40% of police booth have dogs.

= 70 * 2 * 5 + 70 * 10 * 0.4 *2

= 700 + 560

= 1260 dogs -----(3)

### Estimation Question Step-2: Solution

Total Number of Dogs:

= (1) + (2) + (3)

= 2.90 lacs + 36k + 1.26k

= 327.26 dogs
