At Ivy Pro School students are trained not only on latest data Science technologies and tools like SAS,R,Python,Hadoop,Tableau, Machine Learning but also helped to prepare for analytics interviews. This is where preparation on Guesstimates comes in.
One of our previous articles on ‘How to solve Guesstimates‘ talked about how to approach such problems. Lets look at a real example and see how many of you get it right!
We all know about the odd-even rationing in Delhi, just to brief you up:
It is a rule which is implemented to deprive half the population of a particular resource for the benefit of the entire population. The national union territory of India has been devastated with smog in its atmosphere! For the betterment of the dwellers of the city, the government has implemented this rule.
This rule had been declared around 11 months back, now there is a very interesting guesstimate which you might enjoy hacking!
DELHI NCR is the national capital city also known as the national capital territory of India. It is both a city and a union territory of India.
There are many approaches to think about this guesstimate-

Don’t leave it on the D-Day. Practice and practice to perfect your approach
A key to succeeding at guesstimate questions is the adept ability to deal with numbers and swiftly.

You can get the hang of these kind of questions only when you can develop the ability to question and add math to everything.That way you are prepared way beforehand for any curveballs that might come your way during the real interview!
