p = 106, q = 105 এবং r = 104
অনুসৃত সূত্র:
p2 + q2 + r2 - pq - qr - rp = 1/2 [(p - q)2 + (q - r)2 + (r - p)2]
গণনা:
p2 + q2 + r2 - pq - qr - rp
⇒ 1/2 [(p - q)2 + (q - r)2 + (r - p)2]
⇒ 1/2 [(106 - 105)2 + (105 - 104)2 + (104 - 106)2]
⇒ 1/2 [(1)2 + (1)2 + (-2)2]
⇒ 1/2 [1 + 1 + 4]
⇒ 1/2 × 6
⇒ 3
∴ সঠিক উত্তরটি হলো বিকল্প 4
