Question: Count Triangles

Take a look at the figure below. Can you count number of different triangles in this hexagonal pattern?

96. But appears too big an answer.

- Only 3 outer hexagon points: each point makes 4; counted thrice. Unique is 12
- 2 outer hex points + 1 inner hex point: each point makes 4, counted twice. Unique is 18
- 1 outer hex point + 2 inner hex point: each point makes 3, counted once. Unique is 18
- 3 inner hex points: repeat case 1 + 2 + 3 above. Unique is 48.

Question: Counter

How long would it take you to count 1 billion orally if you could count 200 every minute and were given a day off every four years? Assume that you start counting on 1 January 2001.

Question: Counter

How long would it take you to count 1 billion orally if you could count 200 every minute and were given a day off every four years? Assume that you start counting on 1 January 2001.

One, two, three...... two hundred... May take a minute...but when it reaches ninety nine thousand nine hundred eight, ninety nine thousand hundred nine.... it will take much , longer and as you can imagine what would it be when you reach a million... seems may take over a century.....

Did not calculate but if we take that one has to count one, one, one, one, one, 1 billion times and average count is 200 per minute, the answer would be 1 billion diveded by 200 = time in minutes, divided by 60= time in hours , diveded by 24= time in days , divided by 365= time in years. As one day is taken as off every 4 years, so we save the hassle of calculating for leap years.

Question: Counter

How long would it take you to count 1 billion orally if you could count 200 every minute and were given a day off every four years? Assume that you start counting on 1 January 2001.

Solution:

9 Years, 187 Days, 5 Hours, 20 minutes

As you can count 200 per minute, to count 1 billion you require
= 1,000,000,000/200 minutes
= 5,000,000 minutes
= 83,333.3333 hours
= 3,472.2222 days
= 9.512937 years
= 9 Years, 187 Days, 5 Hours, 20 minutes

Question:

Crack the code!

A message is hidden inside the code. Can you decode it?

L4A1Q10P1Q6.. P3M2A3Q3P1P8Z6L7Q3M2Z3P8.. L7A1P5

Solution:

The message is "HAPPY INDEPENDENCE DAY".

The message can be easily decoded using a QWERTY keyboard. Each two characters (except Q10 for P and P10 for Q, which are three characters) represent a letter. The first character of a letter is always Q, A, Z, P, L or M, specifying which row on a QWERTY keyboard the letter is on. The number preceding the letter is the position of the letter on a QWERTY keyboard from left to right (in case of Q, A and Z) or from right to left (in case of P, L and M) along the row. For example, F can be represented as A4 or L6, E can be represented as Q3 or P8.
