- cards =4 [ 1,2,3----------------------13 ]
now jack =11, queen = 12 king = 13& ace = 1 are removed
so sum = 4 [ 2.3.4.5.-----------------10]
= 4 [ 9/2( 2+ 10)] [ sum of A. P.is-- Sn = n/2( a1 + an ]
= 4*9/2* 12= 216 ans

- total no of card 52
16 are removed so remaining 36 cards
sn=n/2(a1+an)
=36/2 (2+10)=216 - 9 years agoHelpfull: Yes(2) No(0)
- jack,queen,king,ace total 22 card remove
then heart 1-10 total= 55, club 1-10 total=55, diamonds 1-10 total=55
55+55+55=165 ans. - 9 years agoHelpfull: Yes(0) No(8)
