Five boys A, B, C, D and E play a game of cards. Each boy has 10 cards. E borrows 3 cards from A and give away 5 to C who in turn gives 4 to B, while B passes 2 to D. How many cards does D have?

Correct answer: 12

Explanation: ✅ Correct Answer: D) 12 📚 Explanation: Every boy starts with 10 cards. E borrows 3 from A, so A has 7. E gives 5 to C, so C has 15. C gives 4 to B, so B has 14. Finally, B passes 2 cards to D. Therefore, D ends up with 10 + 2 = 12 cards. This is a simple tracking problem where you add or subtract from each person's total.
