Answer & Solution
Correct Answer:
Option
A
Cost price of box = Rs. 75
gain% = 8%
Now, required selling price
$$\eqalign{ & = \left( {108\% {\text{ of Rs}}{\text{.75}}} \right) \cr & = {\text{Rs}}{\text{.}}\left( {\frac{{75 \times 108}}{{100}}} \right) \cr & = {\text{Rs}}{\text{.81}} \cr} $$
gain% = 8%
Now, required selling price
$$\eqalign{ & = \left( {108\% {\text{ of Rs}}{\text{.75}}} \right) \cr & = {\text{Rs}}{\text{.}}\left( {\frac{{75 \times 108}}{{100}}} \right) \cr & = {\text{Rs}}{\text{.81}} \cr} $$
