Answer: Option A

Solution(By Examveda Team)

$$\eqalign{ & P.W. = \frac{{100 \times T.D.}}{{R \times T}} \cr & \,\,\,\,\,\,\,\,\,\,\,\,\,\,\, = \frac{{100 \times 168}}{{14 \times 2}} \cr & \,\,\,\,\,\,\,\,\,\,\,\,\,\,\, = 600 \cr & \therefore {\text{Sum}} = \left( {P.W. + T.D.} \right) \cr & \,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\, = Rs.\left( {600 + 168} \right) \cr & \,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\, = Rs.\,768 \cr} $$
