a) Rs. 700
b) Rs. 710
c) Rs. 720
d) Rs. 725
Answer: c
Explanation: Total Cost Price
= Rs. (140 × 450 + 250 × 550)
$$\eqalign{
& = {\text{Rs}}.\left( {63000 + 137500} \right) \cr
& = {\text{Rs}}{\text{. }}200500. \cr
& {\text{Total Selling Price}} \cr
& = {\text{Rs}}.\left( {\frac{{140}}{{100}} \times 200500} \right) \cr
& = {\text{Rs}}{\text{. }}280700. \cr
& {\text{Average Selling Price}} \cr
& = {\text{Rs}}.\left( {\frac{{280700}}{{140 + 250}}} \right) \cr
& = {\text{Rs}}.\left( {\frac{{280700}}{{390}}} \right) \cr
& = {\text{Rs}}{\text{. }}719.74 \approx 720 \cr} $$
