20p and 10p
To make 50p using addition, you can combine different coin values. For example, you could add one 20p coin, one 10p coin, and three 10p coins: 20p + 10p + 10p + 10p = 50p. Alternatively, you could use five 10p coins: 10p + 10p + 10p + 10p + 10p = 50p. There are various combinations of 1p, 2p, 5p, 10p, 20p, and 50p coins to reach the total.
To determine how many 10p coins are in £3.60, you first need to convert £3.60 to pence. Since there are 100 pence in a pound, £3.60 is equal to 360 pence. Next, you divide 360 by 10 (the value of each 10p coin) to find the number of 10p coins. Therefore, there are 36 10p coins in £3.60.
30p = 20p + 5p + 5p 40p = 20p + 10p + 10p
ten 10 x 10p = 100p = £1
The one that is not a 10p is a 20p. The other coin is a 10p. The question/riddle does not say that neither coin is a 10p, only that one of them is not.
A British 10p coin, and all British coins for that matter, are not magnetic.

To make 50p using 1p, 2p, 5p, and 10p coins, you can combine various quantities of these coins. For example, you could use 50 1p coins, 25 2p coins, or 10 5p coins. Additionally, you can mix different denominations, such as 4 10p coins (40p) and 5 2p coins (10p), or any other combination that totals 50p. The total number of combinations can vary significantly based on how many of each coin you choose to use.
