    Question on weight of coins

    In this question:

    1 pence coins weigh 3.5g
    2 pence coins weigh 7g

    A bag contains a mixture of 2 pence and 1 pence coins. It is worth 2. What does it weight?

    I am a little stuck on this one, puzzled... Thanks for any help!

    240 pence in a pound (if I remember correctly). the fact that there are a mixture of 1 and 2 pence coins doesn't matter ... the bag would weigh the same as 2 pounds of 1 pence coins, or 2 pounds of 2 pence coins, or 2 pounds of a mixture of the two.

    In the olden days, certainly. If the question refers to 1p and 2p coins as we have them today, it's 100p=1

    How many 1p coins would you need to make 2?

    Then, how much does a 1p coin weigh?

    Then, how much would "the amount of 1p coins you need" weigh?
