i hope every one will enjoy these riddles
They are not really mine but some of them are
i got looooads so i thought i will start a thread of riddles.
Now lets see...........where shall i start.........
lets start with one of my riddles.......
Once me and my dad was on our way to school in Kuwait.
He asked me that........
I have some apples in my right hand and some in the left hand. Now, if I minus an apple from my left hand and add it to my right hand, then both of my hands has equal no. of apples. And if I minus an apple from my right hand and add it to my left hand, then my left hand contains double the no. of apples as in my right hand. How many apples do I have in each of the hands?
i was verrrrry confused. i went to school and asked my friends but none of them knew the answer. i asked everyone i knew but none of them could get it. but then i came home and asked him for the answer and he told me.........Well i was very small at that time anyway
So give this riddle some tries and i will be back with another brainteasing one insha'allah. But my first 21 riddles are going to be on Maths .
i think riddles are cool but i can never understand them so i try my best to stay away from it but its interesting to read it and see the actual answer so ppl who can actually do it masha'Allah thats cool
Been trying to work out Ansar's question but I'm quite exhausted now after almost having my head exploded. I am VERY near to the answer I think...I just can't find a way to relate the patterns to the value of 'n'.
The least I can do is to tell the areas then:
1st Triangle = 0
2nd = 1/4
3rd = 7/16
4th = 37/64
If that isn't right I think I'll jump out of a window.
Yes, its right, Br. Muhammad. I think I made a mistake in the question about the formula. Two corrections:
-the first triangle is the one with area of 1/4
-derive a formula to find the white area of the next triangle (not needed to relate it to n, only to the area of the previous triangle)

No, the first number in the series should be 1/4, not zero. But either way, since we're asking for a recursive formula, it shouldn't make a difference.

I'm back..........got only one more exam to go and that is the english writing paper.
got nothing to revise so i just thought that i might come and post some riddles......
OK now lets see........
LISA IS LAYING ON THE COUCH ASLEEP AND BOB IS ON THE FLOOR DEAD IN A PUDDLE OF WATER WHAT HAPPENED?
Lets assume Number of White Blocks in the triangle be "X"
n total Number of Blocks be "Y"
so the for the first triangle its : X/Y = 1/4
now to get the number for the next triangle i got the forumla :
[3x+y]/4y
So you're saying that
n=3x+y
........... 4y
where x is the numerator of the previous term, and y is the denominator. Interesting way to tackle the problem.
I'll show how I did it.
If you look at the pattern, you notice right away that the denominator in each term increases by multiples of 4. So I said for the nth term, the denominator is 4^n.
My formula was:
tn= (3^n-1) + tn-1
..............4^n
Where tn is the nth term, and tn-1 is the previous term.
Great job, br. Zak!
