B ∶ C = 7 ∶ 9
গণনা:
অনুপাতগুলি নিম্নরূপ
⇒ A ∶ B = 4 ∶ 5
⇒ B ∶ C = [7 × (5/7)] ∶ [9 × (5/7)]
⇒ B ∶ C = 5 ∶ (45/7)
অতএব, অনুপাত A ∶ B ∶ C
⇒ A ∶ B ∶ C = 4 ∶ 5 ∶ (45/7)
⇒ A ∶ B ∶ C = 28 ∶ 35 ∶ 45
∴ A ∶ B ∶ C = 28 ∶ 35 ∶ 45
বজ্র-গুণন ব্যবহার করে
⇒ A ∶ B = (4 ∶ 5) × 7 = 28 ∶ 35
⇒ B ∶ C = (7 ∶ 9) × 5 = 35 ∶ 45
অতএব, অনুপাত A ∶ B ∶ C
⇒ A ∶ B ∶ C = 28 ∶ 35 ∶ 45
∴ A ∶ B ∶ C = 28 ∶ 35 ∶ 45
