There are two numbers a and b ( a not equal to b ) such that they are having same number of digits and same sum of digits which is equal to 28 . Find the numbers , are they multiple of each other ?
You are provided with a grid (as shown in the picture). Can you fill the squares with numbers 1-8 in a manner that none of the two consecutive numbers are placed next to each other in any direction (vertically, horizontally or diagonally?)
When asked for the sum of two numbers one person said 23 and the other said 210. They were both wrong because they had correctly done the wrong calculation. What were the numbers and what had each done?
