Assuming that the total number of players = x
then (1/4) x are capped
and the remaining (3/4)x are uncapped

half of the capped & all the uncapped are defenders. --> 1/2(1/4)x + 3/4x = Defenders
----> Number of Defenders = (1/8+3/4)x = 7/8 x

IF number of uncapped = 3/4 x = 36 --> x=48
therefore, the number of defenders = 7/8 x = 7/8 (48) = 42
And the number of players who are not defenders = x -42= 48-42= 6

We see that the uncapped players comprise 3/4 of the total number of players in the club. Since there are 36 playes, the total number of players in the club is 36 / (3/4) = 36 x 4/3 = 12 x 4 = 48. That means 1/4 x 48 = 12 players are capped players. Since 1/2 x 12 = 6 of these 12 capped players (and all the uncapped players) are defenders, the remaining 6 capped players are not defenders.
