Hearts and diamonds will be in read and they r 6.
Spades and clubs will be in black and they are 7 in total.
There are twice as many diamonds as spades. menas D = 2S
twice as many hearts as diamonds means H=2D. Out of 6 4 will be hearts, 2 will be diamonds.
if diamonds are 2 then Spades will be 1. so remaining 6 blacks are clubs
