The correct option is A Rs.420
A, B and C shared Rs. 1540.
∴ A+B+C=1540 ...(1)
A received three times as much money as B.
∴ A=3B
∴ B=A3 ...(2)
C's share is half that of A's.
∴ C=A2
∴ A=2C ...(3)
Substituting (3) in (2) we get,
B=2C3 ...(4)
Substituting (4) and (3) in (1) we get,
A=840, B=280, C=420
∴ C receives: Rs.420
