Well Another problem not so hard but just thinking...........
There are 52 cards in a pack of cards. If you turn any 10 cards upside down and place them back(upside down) and give them a good shuffel so that the card are at random. Now from the top of the pile pick 10 cards. Using those 10 cards how can you make the same number of card upside down in each pile, without looking into the rest of the pile....????????
I said that you enter x liters of water the first day 2x on the second day and 4x on the second day. I did'nt say there TOTAL!!!! (it mean you keep doubling the amount of water you enter in the pond each day with respect to the amount of water entered the previous day irrespective of the ammount of water in the pond)
........................SOLUTION.....................................................
work backwards.. that is if a pond fills in 30 days, it will takes 29 days to fill half of it(doubles each day). this means that it will takes 28 day to fill a quarter of the pond and 27 days to fill 1/8th of it...............
Great problems.......
my teacher gave me this problem that
If there is an empty pond and you keep adding water such that if you enter x liters on first day, you enter 2x the second day, 4x on the third and so on.. It takes 30 days to fill a pond. How long will it takes to fill 1/8th the pond..????
its simple problem.. but the solution is a bit hard to figure out.....
this is because by taking any odd number and adding it twice, thrice, 6 times or any number which is even you can get an odd number. i gave you 6 odd numbers and wanted 2 make it odd as well .....................HOW IS THAT POSSIBLE?????
so NO SOLUTION !!!!!!!!!!!!!!!
of course.........
and another way to do this is just to multiply 15ft by 16 ft into are which comes out to be 240sq ft. then multiply that by the area of one meter sq.
1 ft = 0.305m
1sq ft = 0.305*0.305 = 0.093025
multiplying the original are by the are in meter sq , i get 240 * 0.093025 = 22.326m sq..
find the next letter of the sequence......
ze, te, tw, th, fo, fi, si, se, ei,...........
hi

you got 12 numbers which are
1 1 1
