The Answer is 22

Select any 3-digit number with all digits different from one another. Write all possible 2-digit numbers that can be formed from the 3-digits selected earlier. Then divide their sum by the sum of the digits in the original 3-digit number.

e.g.    Consider a 3-digit number 365.
         All possible 2-digit numbers are 36, 35, 63, 65, 53, 56.
         Their sum is 36+35+63+65+53+56=308
         Sum of the digits of original number is 3+6+5=14
         Then 308/14=22

A Few Thoughts

On the previous Puja, I had been writing something about me & my school life. Later I named it “A Few Thoughts” and submitted to my school magazine authority. But it was deselected for publishing due to some vulnerable topics.

One year later, today, I’m publicly sharing this.

Knock-out Cricket Tournament

A single elimination (knock out – one loss & out) cricket tournament has 16 teams competing. How many games must be played to get one champion?

Typically, the majority problem solvers will do something like this –
i) Taking 2 groups of 8 teams, playing 1st round. In each group there are 4 matches, eliminating 4 teams. Total 8 matches & 8 teams remaining in the tournament.
ii) Now 4 Quarter-final matches to get the top 4 teams of the tournament. (8 + 4 = 12 matches so far)
iii) 2 Semi-finals & a final to get the champion. (12 + 2 + 1 = 15 matches total)

A much simpler way to solve this problem is to focus only the losers, not the winners.
“How many losers must be there in a tournament of 16 teams to get one winner?” The answer is simply 15.
“How many games must be played to get 15 losers?” Naturally 15.
That’s the answer.

No Nobel for Mathematics

Nobel prizes were instituted by the will of Alfred Nobel, a Swede who was a chemist, an industrialist and the inventor of dynamite. Since 1901, prizes have been awarded for achievements in Physics, Chemistry, Physiology or Medicine, Literature and Peace – but not in Mathematics. Legend says that Nobel ignored mathematics because his wife rejected him for a mathematician, named Gosta Mittag Leffler. Furthermore, Nobel didn’t consider mathematics a “practical” science that had much impact on society.

That’s why Able prizes have been awarded for achievements in Mathematics.
