A একটি কাজ করতে পারে = 30 দিন
B একটি কাজ করতে পারে = 40 দিন
C একটি কাজ করতে পারে = 50 দিন
অনুসৃত সূত্র:
মোট কাজ = দক্ষতা × সময়
গণনা:
| দক্ষতা | ব্যক্তি | সময় | মোট কাজ |
| 20 | A | 30 | 600 |
| 15 | B | 40 | |
| 12 | C | 50 |
প্রশ্নানুসারে:
⇒ (20 + 15 + 12) = 47 একক = 3 দিন
⇒ 47 × 12 = 564 একক = 3 × 12 = 36 দিন
⇒ (564 + 20 + 15) = 599 একক = 38 দিন
মোট কাজ = 600 একক = 38 + (1/12) = 38\(1\over12\) দিন
∴ সঠিক উত্তর হল 38\(1\over12\) দিন।
