1 . At a dinner party every two guests shared a bowl of rice between them, every three guests shared a bowl of vegetable between them and every four shared a bowl of meat between them. There were altogether 65 bowls. How many guests were present at the party?

• A. 60
• B. 65
• C. 90
• D. 100
• D. None of these

Answer: Option A

Explanation:

Bowl  =  Guests
30  ×  2  =  60 (rice)
20  ×  3  =  60 (vegetable)
15  ×  4  =  60 (meat)
so 30  +  20  +  15  =  60
