Let the weights of the diamonds be k, 2k, 3k and 4k. Total weight of the diamond =k+2k+3k+4k=10k Price of the original diamond =λ(10k)2=₹100λk2 Total price of the four pieces of diamond =λ[k2+(2k)2+(3k)2(4k)2] =₹30λk2 Loss in total value of diamond =100λk2−30λk2 =₹70λk2 ∴70λk2=70000 ⇒λk2=1000 Therefore, price of the original diamond =100×1000 =₹1,00,000
