The price of silver-biscuit is directly proportional to the square of its weight. A person broke down the silver-biscuit in the ratio of 3: 2: 1, and faces a loss of Rs 4620. Find the initial price of silver-biscuit.
Answer & explanation
Correct answer: option 4
Price of biscuit = ( weight of gold)2
I : II : III : Actual
weight ⇒ 3 : 2 : 1 : 6
Price ⇒ 32 : 22 : 12 : 62
⇒ 9 : 4 : 1 : 36
Now,
Actual Price = 36
Price after break = (9 + 4 + 1) = 14
Loss = 36 - 14 = 22R
⇒ 22R = 4620 (given)
⇒ 1R = 210
Hence,
Actual Price = 36 × 210 = 7560/-
