Let 'a' be the number of cards with B. If A gives five cards to ‘B’ then ‘B’ will have as many cards as ‘D’ Hence, the number of cards withD=′a+5′ B has four cards more than what C has. Hence, the number of cards with c=′a−4′. Let us assume that number of cards with A = 'x'. It is given that if ‘B’ gives 'A' five cards the A will have as many cards as ‘E’ has. Hence, the number of cards with 'E' = x+5. t is also given that A and B together has 20 cards more than what D and E have together. Hence, (a+x)−(a+5+x+5)=20. Data given in the question contradicts with th information. Hence, this question can't be answer. Therefore, option D is the correct answer.
