Answer» Correct option (b) B, C and F Explanation: At the start all the boys have equal number of cards, as shown below:
Now, F borrows 2 cards from A and gives away 5 to C who in turn gives 3 to B:
B gives 6 to D who passes on 1 to E.
Number of cards with D and E = 15 + 11 = 26 We can see that number of cards with B, C and F = 7 + 12 + 7 = 26 |
