মনেকরি, ডিমের সংখ্যা = x টি পঁচে যায় = x এর 10% = x/10 টি পঁচে যাওয়ার পর অবশিষ্ট = x - x/10 = 9x/10 টি প্রতিবেশিদের দেয় = 9x/10 এর 80% = (9x/10) × (80/100) = 18x/25 টি অবশিষ্ট = 9x/10 - 18x/25 = (45x - 36x)/50 = 9x/50 টি প্রশ্নমতে, 9x/50 = 36 ⇒ x = (36 × 50)/9 ⇒ x = 200 অতএব, ডিমের সংখ্যা ছিল 200 টি।
