A sold a watch at a gain of 5% to B and B sold it to C at a gain of 4%. If C paid Rs. 91 for it, then the price paid by A is ?
-
- Rs. 82.81
- Rs. 83
- Rs. 83.33
- None of these
Correct Option: C
Let A's C.P. = Rs. 100
B's C.P. = Rs. 105
C's C.P. = 104% of Rs. 105 = Rs. 109.20
∵ 109.20 : 91 = 100 : P
∴ P = (91 x 100) / (109.20) = Rs. 83.33
