    Unless the table was round There are 6 ways

    4 on one side and 1 on the other.
    3 on one side and 2 on the other.
    5 on one side and 0 on the other.
    0 on one side and 5 on the other
    1 on one side and 4 on the other.
    2 on one side and 3 on the other.

  2. Sorry the 600 is in the wrong place it the 6 needs to be in the hundreds column and the 0 needs to be in the tens column also the over 0 needs to be in the units column.

  3. Bronze
    Bronze is wrong because twentyfour is in the wrong place also the four needs to be in the units colum and two needs to be in the tens colum.Also 6×20=120 and the wrong answer is 6×20=112.
    The right answer is:

    124
    x__6
    24
    120
    +_600__
    =144

    The wrong answer is:

    124
    x____6
    24
    112
    +___

  4. Silver
    If the table has a circle shape there wouldn’t be any possibilities. However, my answer is applicable to a square table that has four sides:
    Possibility 1: 1,1,1,2 (on four sides respectively)
    Possibility 2: 2,2,1,0
    Possibility 3: 3,1,1,0
    Possibility 4: 4,1,0,0
    Possibility 5: 3,2,0,0

  5. Bronze
    The calculation is incorrect because 6 x 20 is 120,not 112
    and the number 24 should be in the Tens and Units column.
    124 x 6 = 744

    Silver
    There are 7 ways.
    3 on 1 side and 2 on the other.
    2 on 1 side and 3 on the other.
    4 on 1 side and 1 on the other.
    1 on 1 side and 4 on the other.
    5 on 1 side and 0 on the other.
    0 on 1 side and 5 on the other.
    1 on your right,2 on your left and 2 on your front.

    Gold
    £60 with 20% off is
    60-12=£48

    £40 with 10% of is
    40-4=£36

    £55 with £16 off is
    55-16=£39

    The best offer is £55 with £16 off because more money has
    been taken of than the other offers and I could save the
    rest of my money.

  6. Bronze

    The final answer for this question (which is 736) is incorrect because the correct answer is 744. Some parts of the question are correct and some are incorrect. The correct parts of the question are (6×4=24 and 6×100=600). However, the wrong part of the question which made the total wrong is (6×20=112). See below my answer:
    1 2 4
    6 x
    2 4
    1 2 0
    6 0 0 +
    7 4 4

  7. Gold

    1)60X20=1200
    1200/100=£12

    2)40×10=400
    400/100=£4

    3)55-16 =£39
    If I go to a shop I will choose the second offer (£40 with 10% off) because it is the cheapest.

  8. silver
    5 on 1 side and 0 on the other.
    4 on 1 side and 1 on the other.
    3 on 1 side and 2 on the other.
    2 on 1 side and 3 on the other.
    1 on 1 side and 4 on the other.
    0 on 1 side and 5 on the other.
    gold
    the best offer is £55 – £16 = £39.
    compared to the other offers price this is the smallest.

    this is wrong because the tens are in the hundreds collom.

  9. It’s £40 with 10% off because £60 with 20% off is £48 because you count in six times table so 6 is 10% of the six times table because it is like 6×2=12 but it is 20% because the clue is the number that you are not doing you’re. Times table is how much % you’ve got but just add the place value so 6×2=12 so it’s 12 pounds off so it equals £48.Next is £40 with 10% off so it is 4×1=4 so its £4 off which is £36 and last one is £55 with £16 off which is £39 so it is £40 with 10% off
    Silver
    There a five ways
    1 2 3 4 5
    2 3 4 5 1
    3 4 5 1 2
    4 5 1 2 3
    5 1 2 3 4
    Those are the five ways
    Bronze
    It’s wrong because 4×6=24 so that is correct
    Next is 20×6=120 but it says 112 so that is wrong
    Finally its 100×6=600 so that is right and the adding up is right but just 20×6 let you down to get the answer wrong.

  10. Gold
    £55 with £16 off is the best offer because £60 with20% off gives a saving of £12 and £40 with 10% off gives a saving of £4.

    Silver
    If I seated my guests using the long sides of the table their would be 6 possibilities.
    4 on the left side and 1 on the right side.
    3 on the left side and 2 on the right side.
    2 on the left side and 3 on the right side.
    1 on the left side and 4 on the right side.
    5 on the left side and 0 on the right side.
    5 on the right side and 0 on the left side.

    Bronze
    The sum is wrong because your digits are in the wrong place,24 ment to be in the tenths and units column.so the 24 is above the 12 in 112.
    And your 112 and 600 are in the right place.
    You didn’t put your numbers in the right place but you got your sum correct.

  11. GOLD
    The best offer is 55 with 16% off because 16×4=56
    The good offer is 40 with 10% off because 10×4=40
    The wors offer is 60 with 20% off because 20×3=60

  12. GOLD
    The best offer is 55 with 16% off because 16×4=56
    The good offer is 40 with 10% off because 10×4=40
    The wors offer is 60 with 205 off because 20×3=60

  13. Bronze
    The calculation is wrong because, 6 multipled by 20 is 120 not 112. In your calculation your addition is right however, 24 is in the wrong colum and the correct answer is 744

  14. Gold
    the 2nd deal is the best because deal 1 equals £40 and the first one equals £38.

    Silver
    3’on one side 2 on the other.
    2 at the front 3 at the side.
    5 on 1 side.
    1on one side 4 on the other.
    2 on each side and one by himself.

    Bronze
    The answer is wrong because
    6 x 20 = 240 then

    124
    x __6
    2 4
    1 2 0
    6 0 0
    = 744

  15. Gold

    The best offer is £55 with £16 off because £16 will be off and I could save the rest of the money.

    Silver

    To seat five guests on one table you could do:
    • 3 guests on the right hand side and 2 on the left hand side
    • 3 guests on the left hand side and 2 on the right hand side
    • 4 guests on the left hand side and 1 on the right hand side
    • 2 guests on the right hand side then 2 more guests on the left hand side and then 1 guest on the other side. (This table will be in a rectangle shape)

    Bronze

    The calculation is incorrect because the number 24 is in the wrong column. The real answer is 744.

  16. Silver

    Five people could sit on one table,by 3 people on one side and 2 people on the other. Or you could have 1 on one side and 1 on the other than to on one side and to on the other.
    Gold
    40 pounds with 10% of is the cheapest because it is cheaper than the rest

  17. GOLD
    £60 divided by 100 x 20 = 12
    60-12= 48

    £40 divided by 100 x 10 = 4
    40-4=36

    £55 divided by 100 x 16 = 8.8
    55-8.8=46.2

    So percent wise 20% offer is the best and price wise £40 offer is the best because we only spent £36.
