123 - 45 - 67 + 89 = 100

29 is correct Sekhar and Kid!
Next...
1 2 3 4 5 6 7 8 9=100
Make the above equation true by placing the minimum number of mathematical signs, do not use complex symbols and formulae! Also 'inequality' is ruled out!

Cool!
Another easy one...
Multiplying a two-digit number with 7 yields a 3-digit number. Placing a 6 at the end of the 3-digit number increases it by 1833. Find the original 2-digit number.

x = 2[y - (x-y)]
x + y = 49
solving
x = 28
y = 21

Posted by: Hytech At: 13, Nov 2003 11:05:11 PM IST
