ZS Associates Guess Estimate Information

In ZS Associates there will be puzzle like questions, where you are expected to estimate is supposed to be determined by placing a structure to a question, forming segments, making assumptions .

While answering the questions if you say wrong answer with a better approach will be considered but if you say wrong answer with a bad approach it will lay a negative impact of yours. The most important thing that matters here while answering the questions is a good approach.

Tips and Tricks to Solve ZS Associates Guess Estimate :-

  1. Clarify:- First understand the question try and extract the exact information from the question that what you need to calculate. Suppose there is a question how many people in India consume a cup of coffee.
  • In the tea estimation problem, the population of India is a good proxy to find the number of cups of coffee consumed monthly in India.If the person will consume coffee then they will consume atleast two in a day or more than 2. But we will the take the average as 2.
  • If the population of India increases, it can be safely said that coffee consumption will increase proportionally.

    2.Analyze and Breakdown the Problem:-  Then you need to break down the problem into pieces.

  • Total Population of India.
  • Total Number of People like to drink tea in India.
  • How many cups of tea are consumed daily.

     3. Do smart calculations and round off:-  Speed is really essential and a balance between the consumption of time needs to be maintained. Suppose you need to calculate 599/2 then first do 600/2 =300 and then you can calculate by doing minus 1. so it will be around 299.

    4.Validate number magnitude: – It is always a good idea to keep on validating intermediate numbers using your experience and sense checks.

ZS Associates Guess Estimate Questions:-

  1.   What is the guesstimate for the number of laptops sold in Delhi on an average routine day?

Solution:-

Take two sides of this into consideration – demand and supply. I assume demand </= supply, since the location listed is Delhi. Let us concentrate, then, on the demand side, because it is the guiding power.

Starting with the Delhi population
= X = 20 million.

A laptop is used by a student or a working professional, i.e. persons belonging to the 18-45 age group, representing approximately 70% of the population of Delhi.

Assuming a laptop’s average cost is about 30k INR and assuming that a typical Indian spends around 10 percent of the annual revenue on electronic devices, a laptop buyer’s annual revenue could be about 4 lacs.This comprises about 70 percent of the population of a city like Delhi.

Assume that 70 percent of this population currently has a laptop and thatin a given year just 30 percent expect to purchase a new one.

Assume a PC will be purchased by 20 percent (20 percent as laptop popularity increases), a laptop will be bought by 80 percent.

So average number of laptops sold in a given year in Delhi = 0.7*0.7*0.3*0.8*X = 2,35,200.

In a year = 235200/365 = 645 = Y

Now,

  • On weekdays, this number will be around 80% of it = 516
  • On weekends, this number might shoot up by 30% = 838.5
  • On festivals like Diwali and Christmas, sales might increase by 40% = 903 .

 

     2. You have two buckets that hold 3 lit. and 5 lit. How do you fill 4 lit?

Solution:-

Firstly Fill the 3L bucket FULL. Then transfer this water to a 5L bucket. It now has 3L. Fill 3L bucket FULL again. Transfer to a 5L bucket till it fills completely. Now the 3L bucket has 1L. Throw away 5L of water. Transfer 1L water from 3L to 5L. Fill 3L bucket FULL again. Transfer to a 5L bucket to get 4L in the bucket.
