    A shopkeeper likes to arrange and rearrange his collection of stamps. ...
    Solution:

    Let's assume that the shopkeeper has 'x' number of stamps.

    Arrangement in Pair:
    If he arranges them in pairs, then the number of stamps should be an even number. Therefore, x is even.

    Arrangement in Bundle of Three:
    If he arranges them in bundles of three, then the number of stamps should be a multiple of 3. Therefore, x is a multiple of 3.

    Arrangement in Bundle of Four:
    If he arranges them in bundles of four, then the number of stamps should be a multiple of 4. Therefore, x is a multiple of 4.

    Arrangement in Bundle of Five:
    If he arranges them in bundles of five, then the number of stamps should be a multiple of 5. Therefore, x is a multiple of 5.

    Arrangement in Bundle of Six:
    If he arranges them in bundles of six, then the number of stamps should be a multiple of 6. Therefore, x is a multiple of 6.

    Arrangement in Bundle of Seven:
    If he arranges them in bundles of seven, then the number of stamps should leave no stamps in hand. Therefore, x is a multiple of 7.

    To find the value of x, we need to find the LCM (Least Common Multiple) of 2, 3, 4, 5, 6 and 7 since x is a multiple of all these numbers.

    LCM of 2, 3, 4, 5, 6 and 7 is 420.

    Therefore, the shopkeeper has 420 stamps.

    But we know that every time he arranges them in bundles, he is left with one stamp in hand. Therefore, we need to subtract 1 from 420 and check if the result is a multiple of 7.

    420 - 1 = 419

    Since 419 is not a multiple of 7, we need to keep subtracting 420 from the number until we get a number that is a multiple of 7.

    419 - 420 = -1 (not a multiple of 7)
    -1 - 420 = -421 (not a multiple of 7)
    -421 - 420 = -841 (not a multiple of 7)
    -841 - 420 = -1261 (not a multiple of 7)

    Now, if we subtract 420 from -1261 once again, we get a number that is a multiple of 7.

    -1261 - 420 = -1681

    Therefore, the shopkeeper has 1681 stamps.

    But we know that every time he arranges them in bundles, he is left with one stamp in hand. Therefore, we need to subtract 1 from 1681 and check if the result is a multiple of 7.

    1681 - 1 = 1680

    Since 1680 is a multiple of 7, this is the correct answer.

    Therefore, the shopkeeper has 1680 + 1 = 1681 stamps.
