How many medium size pan tossed pizza are sold in Mumbai on Sunday?
Me: It was guesstimate question wherein your approach is given more importance as compared to your final answer. My approach was as follows
TOP DOWN Approach
- Rounding off Population of Mumbai
- Dissected them in various age groups
- Further dissecting them according to their food preference north Indian, South Indian, Italian and so on.
- Dividing Sunday into various shifts → Lunch, Snacks, Dinner
- Then taking a calculated guess as to how many people would prefer a Pizza in those shifts and adding those people.
- Dividing the above number by 2 because Medium Size can feed approximately 2 people.
I was also asked what could be an alternative solution. In that case, you had to do BOTTOM UP approach.
Few days before my interview, Star had won the rights for IPL for Rs 16,347.50 crore over the next 5 years from 2018 to 2022.
How much money will be paid by Star network for per ball bowled in IPL 2018?
- Approx 15,000 Crores for 5 years
- Hence 3,000 Crores per year
- 60 matches per season hence 50 Crore/ Match
- Per match approx 240 Balls are bowled hence approx 20,00,000 Rs/ Ball Bowled (Actual Answer is 22,70,000 Rs/ Ball)

Interesting article. For the last question - According to me, no. There shouldn't be an expedition - 1. Uranus is way too far off to have global space agencies send a manned mission to. It will take almost a decade for the team to reach, collect the diamonds, and another decade to come back. That's 20 years in Space constantly. Astronauts are likely to undergo muscle atrophy in such a scenario (even if they exercise regularly). They will also be exposed to radiation in space, which can be lethal. Additionally, there is the problem of Uranus's century-long orbit of the Sun, making it even more difficult to reach the planet. 2. Uranus is a gas giant with no solid surface to land on. The atmospheric pressure will crush anything that attempts to enter its orbit and collect diamonds, and it will be an almost impossible task. It will be very difficult to send robots to do the task as well. 3. The diamonds themselves may not be of the composition that we assumed them to be. By this logic of raining diamonds, we should go on an exploration of an entire planet made of diamonds which is a few light years away. But it is illogical to do so.
