Brain Teaser by mormoni(m): 8:09am On Feb 15, 2015
A boy forgot his pin code which is 5 digits, but luckily he remembered some hints on how to recall the pin code. Here are some of the clues:
1) The first digit is the square of the 2nd.
2) The sum of the 2nd and 3rd is 10.
3) The 4th is equal to the 2nd plus 1.
4) The 3rd and 5th makes 14.
5) The sum of all the digits is 30.

Now what is the code?

I can now see why some people don't finish there examination questions b4 the alloted time. Using matrix is quite correct. But simple and Common sense demands that u think simply.in the question,the possible combinations(3) of the 3 animals in pair as been given already. To find the total weight of the animals,simply find the sum of the total weight of 3 combinations.I.e 10+20+24=54. Then divide the answer by 3(animals involved or possible combinations or possible outcome depending on the statement given).I.e 54÷3=27.
