Correct answer is: 255 Explanation: Final price in 1st case = 70% of 90% of 90% of Rs. 10000 $\eqalign{ & = {\text{Rs}}{\text{.}}\left( {\frac{{70}}{{100}} \times \frac{{90}}{{100}} \times \frac{{90}}{{100}} \times 10000} \right) \cr & = {\text{Rs}}{\text{. 5670}}{\text{}} \cr}$ Final price in 2nd case = 95% of 95% of 60% of Rs. 10000 $\eqalign{ & = {\text{Rs}}{\text{.}}\left( {\frac{{95}}{{100}} \times \frac{{95}}{{100}} \times \frac{{60}}{{100}} \times 10000} \right) \cr & = {\text{Rs}}{\text{. 5415}}{\text{}} \cr}$ ∴ Money saved by choosing the better offer = Rs. (5670 - 5415) = Rs. 255 Nithin ? answered undefined All Comments
