Compute the total number of possible pocker pairs (two cards with the same number) that can be obtained when taking two cards from a standard deck. Recall that a standard deck of cards consists of 52 cards, numbered A, 2, 3, . . . , 10, J, Q, K and there are 4 suits: clubs, hearts, black hearts and diamonds. The closest number of pairs is: (A) 78
(B) 158
(C) 76398
(D) 467
(E) 1254

When 142 is added to a number the result is 64 more then 3 times the number. option 35 37 39 41
