Country : India | megu posted @ 2014-05-25 6:17 PM I have a query in A2 Match the following puzzle. I have submitted the answer as ZYWX and I haven't got any points for that.
I arrived at the result as follows:
2 + 3 x 6 / 9 = 4
4 x 5 / 2 - 7 = 3
5 x 3 - 9 / 6 = 1
6 / 2 + 7 - 8 = 2
What is the right answer?

Without releasing right answer yet, I'll give you a chance to solve it yourself. You've missed the rule that operator precedence is followed, i.e., Multiplication and division are done before addition and subtraction. So your equation for 1 will actually become 15 - 1.5, not 6/6. |

5 x 3 - 9 / 6 is (5 x 3) - (9/6) = 15-(3/2) = 13.5

Country : Canada | Equation 3 is wrong, since you need to respect the order of operations, which gets you 13.5.

Country : India | megu posted @ 2014-05-25 7:09 PM Oh! I get it now! How silly of me!
I applied the operator precedence rule in other 3 parts and failed at one part.
I solved it now, I hope I have got it right this time:
2 + 3 x 6 / 9 = 4
4 - 5 x 2 + 7 = 1
5 - 3 / 9 x 6 = 3
6 / 2 + 7 - 8 = 2
I will have to keep in mind to re-check everything before submission for future contests, however few puzzles I am able to finish.
Thank you for the reply. Also thanks to the other two people who replied.

Country : India | In E1 Star battle my logic went like this.
1. Every region need to have 6 stars.
2. At C2 there must be a stars.
3. The same region holds 2 stars at column A and D.
4. So one star must be at B or C9.
5. The other small region holds 2 stars at column F and H.
6. One star at G 5/6/7.
7. One at I 2/3.
But i wasted hell of time and could not finish the puzzle. Can any one guide me were I went wrong. |

You haven't gone wrong anywhere so far, but you can reduce things more. Remember that there can be only one star for each 2x2 area of cells. Dividing the "K" shape into this distribution helps - 1 star in I23/H3. 1 star in H34. 1 star in F34. One star in F56/G56. One star in F78. One star in H78. (G7 cannot be a star because you need 2 stars in F78/G7/H78 and this will contradict things ). You should be able to reduce it further from here. |

Country : India | G6 also cannot hold a star. If we place a star at G6, F8 and H8 must hold a star, this restricts placing any star between E9 and I9. Is this logic correct. |

No, you can still fit 2 stars in the remaining 4 cells of the row, A/D9 and B/C9. You can reduce it elsewhere on the K. |

Very nice puzzles! My only complaint is with Coded TomTom puzzle (C3 ). Symbol for division looks very similar to plus symbol. Maybe next time using / symbol for division might be better. Edited by Gotroch 2014-05-26 1:17 PM
