Solution

The correct option is E JKQA

As per the above tree diagram, in one suit of $13$ cards, there are $4$ lettered cards (Jack, King, Queen and Ace), and the letters on them are J, K, Q and A, respectively. Therefore, one of the possible concatenations of the letters in one suit is $‘ ‘ JKQA "$ .

Similarly, from the above tree diagram, it is clear that in one suit of $13$ cards, there are $9$ numbered cards from $2$ to $10$ .
Therefore, the sum of all the numbers in one suit = $2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10 = 54$ .
