Download Solution PDFகொடுக்கப்பட்டவை:
p = 106, q = 105 மற்றும் r = 104
பயன்படுத்தப்படும் சூத்திரம்:
p 2 + q 2 + r 2 - pq - qr - rp = 1/2 [(p - q) 2 + (q - r) 2 + (r - p) 2 ]
கணக்கீடு:
p 2 + q 2 + r 2 - 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 ⇒ 3
∴ சரியான பதில் விருப்பம் 4 ஆகும்.
