Puzzle : Sequence of numbers

Sequence of numbers are 1, 11, 21, 1211, 111221. What will be the next one in the above sequence?

 It is a strange sequence. Each number describes the resemblance of the previous one, except the first one.


11 describes the previous '1' which contains one '1'


21 describes the previous '11' which contains two '1'


1211 describes the previous '21' which contains one '2' and one '1'


111221 describes the previous '1211' which contains one '1', one '2' and two '1'.

Q:

Puzzle : Blueberries and Cups

Maria have some blueberries and some cups. If she put 9 blueberries into each cup she will have two cups left. If she put 6 blueberries into each cup she will have three blueberries left over.

Answer

The number of blueberries is equal to number of cups multiplied by 4 minus one left.


That is :


      B = 9(C - 2) -> (1)


Then the number of blueberries will be equal to the number of cups times three plus one left.


That is :


      B = 6C + 3 -> (2)


Now substitute the 1st and 2nd equations:


      B = 9(C - 2)


      B = 6C + 3


      C = 7, B = 45.


Therefore Blueberries = 45 and cups = 7.
