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?

It could be worse: we could adopt the euro...
