10% of 50 coins is/are 5 coins. So, 5 coins are pennies.
40% of 50 coins is/are 20 coins. So, 20 coins are dimes.
The number of nickels is (5 + 9) = 14, according to the condition.
Then quarters are the rest (50 - 5 - 20 - 14) = 11 coins.
Now you can easily calculate the total and answer the question
