A একটি কাজ সম্পূর্ণ করতে পারে = 18 দিনে
B একটি কাজ সম্পূর্ণ করতে পারে = 12 দিনে
অনুসৃত সূত্র:
মোট কার্য = দক্ষতা × সময়
গণনা:
| দক্ষতা | ব্যাক্তি | সময় | মোট কার্য |
| 2 | A | 18 | 36 |
| 3 | B | 12 |
প্রশ্ন অনুযায়ী:
⇒ (B × 4) + A × D = 36
⇒ (3 × 4) + 2 × D = 36
⇒ 2 × D = 36 - 12
⇒ D = 24/2 = 12
∴ সঠিক উত্তর হল 12 দিন।
