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 let’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 length of roads in Delhi. Check out the step-by-step answer created by Mobiprep experts.
Estimation Question Step-1: Segmentation
Approach:
We will begin with estimating total area ------> area of the roads ------> length of the roads
Assuming, Delhi to be a square and yellow & blue metro lines run diagonally to each other having an average of 30 stations situated in Delhi with an average distance between then to be 2 km.
Therefore, area of Delhi = 1/2x(2x30)x(2x30) = 1800 sq. km
Therefore, area of Delhi roads = 360 sq. km (approx)
Estimation Question Step-2: Solution
Average width of National = 25 mtrs (they are broadr as they are multi- Highways & flyovers lane highways and expressways)
Therefore, length of road = 0.2x360x1000/25 = 2880 km (approx)
Average width of state = 15 mtrs (they are generally smaller in width than NH) owned roads
Therefore, length of road = 0.3x360x1000/15 = 7200 km (approx)
Average width of MCD = 10 mtrs (they are smallest compare to all) owned roads
Therefore, length of road = 0.5x360x1000/10 = 18000 km (approx)
Therefore, the length of roads in Delhi = (2880 + 7200 + 18000) = 28080 km (approx)
