## Maths and Cricket

Here are some problems based on cricket match which can be solved using mathematics only so have fun solving them.

Problem 1: I wanted to gamble in a match between India and England. The odds were 2:1 i.e., if I bet 100 on India, I get 200 more. If I bet 100 on England I get 100 more. If I invest RS. 50 each on both the countries and if India wins I gain 100 rupees on India and loose 50 on England. Hence my total profit would be RS. 50/- (+100-50). But if England wins, there would be neither profit nor loss (-50+50). What would be the safest bet to get the maximum profit? How much I should bet on India and England so that I get maximum amount, irrespective of which country wins.

It was just posted to develop mathematical skill with this example i am not promoting gambling here.

Problem 2: Think before answering. It is not as simple as it appears to be. Take time and think: In a fifty over one-day international match, 49.4 balls are bowled. Last two balls… Seven runs to win… it is ninth wicket partnership… Last two batsmen are at 94 runs each. The team won and both batsmen made centuries. How could it be possible? Don’t think of a no-ball, free hit wide, hitting the helmet etc because… on no-ball if the batsman hits a six it adds 7 (seven) runs to the team score and it wins. Then how the runner also gets 100 runs? This puzzle is more complicated than what you think. Try.

Comment down the solution if you get  it.

## Interesting and Amazing Facts About Maths

Words such as formula, equation and calculation sounds boring for those who hate Maths as a subject so here are some of the mind boggling facts about maths which are really very interesting. Lets have a look

1. Zero is the only number that can’t be represented in roman numerals. 2. 2 and 5 are the only prime numbers that end with a 2 or a 5.
3. The opposite sides of a dice always add up to seven. From number 0 to 1000.
4. An icosagon is a shape with 20 sides.
5. 40 when written “forty” is the only number with letters in alphabetical order, while “one” is the only one with letters in reverse order.
6. In 1900, all the world’s mathematical knowledge could be written in 80 books; today it would fill more than 1,00,000 books.
7. Zero is the only number known with so many names which include zip, zilch, nil, nought, naught.

1. If you write out pi to two decimal places, backwards it spells “pie”.( 3.14 = PIE.)
2. if you multiply 111,111,111 by 111,111,111, this becomes equal to 12,345,678,987,654,321 it also works for smaller numbers: 111 × 111 = 12321.
3. Abacus is considered the origin of the calculator.
4. Have you heard about a Palindrome Number? It is a number that reads the same backwards and forward, e.g. 12421.
5. The number 9 is believed to be a magical number with certain very interesting properties. This is because if you multiply a number with 9, and add all the digits of the resulting number, the sum would always come out to be 9.
6. Here is an interesting trick to check divisibility of any number by number 3.A number is divisible by three if the sum of its digits is divisible by three (3).
7. What comes after a million, billion and trillion? A quadrillion, quintillion, sextillion, septillion, octillion, nonillion, decillion and undecillion.
8. Among all shapes with the same area circle has the shortest perimeter.
