Answer:

Correct option is

B

100000 Rs

Let, the weights of the four pieces of the diamond x,2x,3x,4x respectively.

∴ Total weight of the original diamond=x+2x+3x+4x=10x

Let, price of the original diamond=k(100x

),wherekisconstant

∴ Cost of four pieces=k(x

+4x

+9x

)

=k(30x

)

Loss in the total value of the diamond,

k(100x

2

)−k(30x

)=70000

⇒k(70x

)=70000

⇒kx

=Rs.1000

Hence, price of the original diamond=k(100x
