The number of Rishab’s basketball cards is ¾ the number of Dravid’s cards. If Rishab gives ½ of his cards to Dravid, what will be the ratio of Rishab’s cards to Dravid’s cards

Answer 1

r = 3/4 d
(r/2) / (r/2 + d) = (r/2) / (r/2 + 4r/3) = (1/2) / (11/6) = 3/11
check
suppose r=12 and d=16
then 6/(6+16) = 6/22 = 3/11
