Example

For example, if you are asking the person how many people are in a room, you could start by saying, “There are 5 people in the room, and there are 8 people in the room.” Then you could give a number to prove that your answer is right. For example, you could say, “There are five people in the room and there are seven people in the room.” The reason for the difference is that I added one more person to the room and I had to add one more person to the room. Or you could show the person that your answer is wrong by giving them a counterexample.

Top 8 Guesstimate Questions and Answers:

1 – How many washing machines are bought every year in India?

First, please specify whether we will only examine washing machines made in India or both domestically and abroad.

If we are taking both into account, we will then omit segments depending on a few criteria. While dividing the population of India, keep in mind that there are typically 4 people living in each home. Include the annual need for new refrigerators and replacements in your estimate as well.

In your calculations, take into account the typical lifespan of a refrigerator (10 years) and the anticipated annual growth rate of refrigerators.

2 – Amount of coffee consumed in India per day

Let’s say that 20 percent of the 140 crore people in the nation do not drink coffee. Out of the remaining group, 10% don’t drink coffee, 20% drink it rarely, and 30% drink it every day. Let’s assume that daily coffee drinkers might have three cups per day, whereas infrequent coffee drinkers might have two cups per week.

3 – What is the weight of a Taj hotel?

This is one of the examples of a guesstimate that the interviewer will use to gauge the importance of several considerations. You would also consider the hotel’s dimensions and the weight of the materials used to create the hotel when approximating such a question. The ultimate estimation of the hotel’s weight will also depend on whether there are people within the structure or not.

4 – Number of people that live in your housing society

Imagine a society where everyone lives in apartments. Remember that there is 40 apartments total because they are number from 1 to 40. 9 floors and 3 units make up each apartment building. 9 × 3 x 40 equals 1080 flats.

Indian homes typically have 5 people in them. Unoccupied apartments are possible. if we assume that ten percent of units are vacant. Hence, the total population of the society will be 1080 * 0.9 * 5 = 4860.

5 – How many cricket balls can fill up an average-sized room?

 You must first be aware of the size of the cricket ball. Either ask the interviewer or presume its magnitude are viable options.

Calculate the room’s volume now and divide it by the volume of the balls. Because the balls are spherical, a regular arrangement will result in space because of their shape.

The cricket ball appears to take up 4 cubic inches of space; 1000 balls would fill the same amount of space.

6 – How many hp laptop users exist in India?

First, clarify that the question includes all models of hp laptops. Second, determine the population. India has approximately 140 crore people, with about 40 percent being children and the elderly, so we won’t count them. Assume the percentage of office goers and students who use the laptop. The people below the middle class and be eliminated in this guesstimate. This gives us precisely the market of hp laptops in India.

Know the population of Bangalore. Consider the average family size. Know the percentage of middle and upper-class families excluding families from below the poverty line. Multiply the total families you got by the population of Bangalore.

8 – How many sanitary pads are disposed of in India every month?

We know that the population of India is 140 crores. To solve this type of question, we must also know the man-to-women ratio in India which is 1020 women for 1000 men. It is safe to say that the ratio is almost 50:50 which makes the women population in India more than 70 crores. Finding out teens and adults from it by guessing the correct percentages. If a female uses 15 pads per month. Then multiplying the population with this number will give us the number of pads.
