Bag A contains 8 red balls and ‘x’ blue balls, and bag B contains ‘y’ red balls and 8 blue balls. When all the balls of bag A and bag B are poured in bag C, the probability of taking out 1 red ball from bag C is 6/11. If the sum of ‘x’ and ‘y’ is 28, then find the total number of balls in bag A initially?
