Answer:
he has 6 coins in his pocket
the number in his wallet is unknown
Step-by-step explanation:
Since there are equal numbers of coins, we can deal with them as a group. One group consisting of a nickel, dime, and quarter has a value of 40 cents. Since the total value of the coins is twice that, the man has two groups of 3 coins in his pocket, or 6 coins.
