Online Logic Challenge



due to public demand, we present to you a pure and brain-twisting logic challenge, and the best part- it's online. send your answers to eesa.crce@gmail.com....here we begin-

0. It's my birthday today and i got myself a square birthday cake. it measures 24 cm by 24 cm with a height of 12 cm. we have three people who want to eat the cake equally. but only equal parts won't suffice us.The cake has dark chocolate frosting on all sides except
the bottom and each of us wants to have the same amount of chocolate frosting as
well as the same amount of cake. also there is a mouse made of icing in the center
of the top of the cake, and i ( as i am the birthday boy ) wants the entire rose, no cut may pass
through or touch where the mouse is. so how will you divide the cake???


10. News flash: Martians have invaded earth and taken some of CRCE students as prisoners. The prisoners are put in circular cells which are suspended . The cylindrical wall of the martian cell has four push buttons placed symmetrically. the buttons have two
states ,"1" or "0". But the occupants would not come to know, by any means,
what state the button holds at that time. The CRCE students would be free if the push
buttons are all in the same state, i.e. all "1" or all "0". They are allowed
to press any button any number of times in a bid to get free. But the problem is
after every wrong attempt, the wall of the cell will spin for 30 seconds and therefore the students will have no way of telling which buttons they tried. an attempt consists of 1,2,3 or all four of the buttons being pushed simultaneously. When a button is pushed, its state changes, i.e. 1 becomes 0 and vice versa. Tell whether they will be able to get out of the cell within 5 minutes!!!

1110. There are n coyotes and a roadrunner in a room. All coyotes are free to eat the roadrunner if they are hungry. Now if the roadrunner is eaten by a coyote, that coyote turns sleepy and hence is prone to be eaten by another hungry coyote. A coyote which eats another coyote also gets drowsy. Assume that all coyotes are sane and logical. Can the roadrunner survive at all? Justify your answer.

3110. you have 12 coins with you. can you construct a square and place coins on the sides, such that there are 5 coins on each side.

132110. give me the next number in the series:

1, 18, 35, 66, 176, 190, 408, ?


_______. if you noticed the question numbers are somewhat weird in this quiz...give me the question number of this question !!!


7. dexter comes to a shop in bandra to buy a few items. He chooses 4 things to buy. The shopkeeper tells dexter that he has to pay 7 Rupees and 11 paise. but dexter has only Rs 10 note . Now the shopkeeper in his boredom wants to confuse dexter and test his IQ. He tells him he
