    rope problem

    Leroy has a rope that is 7 inches long. His brother has a rope that is 4 inches longer. How many inches long is Leroy's brother's rope?

    I am told the answer is one, I do not see how this is physically possible. Is this the correct answer?

    the answer is pretty clearly 11 inches.

    Whoever told you 1 inch is wrong.

    Re: rope problem

    Since you posted this under the subject of math puzzles let's be imaginative. Perhaps Leroy has more than one brother. It's possible that one brother has a rope that is 11 inches long and a second brother has a rope that is 1 inch long. Of course under this scenario any answer would be correct, as we have no information on what the second brother has.

    Or perhaps the trick here hinges on the fact that the units for the answer of "1" is not given. Consider this example: if Leroy's rope is 7 inches and his brother rope is 5 inches longer, then the answer of "1" would be correct ... 1 foot that is. Now I know 1 foot = 12 inches, not 11, but perhaps the trick is to use a unit of measure equal to 11 inches.

    Or, simply, the number "11" got misprinted as "1".
