Problem number 2. The two kangaroo coins with the question marks on them have the same value. What is this value? We see that the total value of the coins is 51, and some of the coins are already marked. These two coins have the same value, so once we find how much is missing from the left side to be equal to 51, we'll just need to divide it by 2 to get the value of each one of these coins. So the coins that we know the value of are worth 20 plus 10 plus 10 plus 1, which is 41. The total is 51, so the two coins together need to have a value of 10. Since they both have the same value, each one has a value of 5, because 5 plus 5 is 10. The answer is C.
