उत्तर

\[\text { Let the total number of toffees bought be x } . \]

\[\text { Let  }\frac{x}{2}\text { toffees at the rate of 11 are bought for Rs . 10, and } \frac{x}{2}\text { toffees at the rate of 9 are bought for Rs . 10 }\]

\[\text { Total money spent on buying the toffees } = \left( \frac{x}{2} \right)\left( \frac{10}{11} \right) + \left( \frac{x}{2} \right)\left( \frac{10}{9} \right)\]

\[ = \frac{200x}{198}\]

\[ = \frac{100}{99}x\]

\[\text { It is given that x toffees are sold at one rupee per toffee } . \]

\[\text { Therefore, the selling price of x toffees = Rs . x } \times 1 = Rs . x\]

\[\text { As C . P is more than S . P, it will be a loss } . \]

\[\text { Loss = C . P - S . P }\]

\[ = \frac{100}{99}x - x\]

\[ = \frac{100x - 99x}{99}\]

\[ = \frac{x}{99}\]

\[\text { Loss % } = \frac{\text { Loss }}{C . P} \times 100\]

\[ \frac{\frac{x}{99}}{\frac{100x}{99}} \times 100 = 1  \]%

\[\text { Total loss on the whole transaction would be 1 % } . \]
