A) Rs.11
B) Rs.10
C) Rs.8.10
D) Rs.12
Correct Answer: B
Solution :
Let MP be Rs.\[x.\] Then, \[\left\{ \frac{x}{(100+x)}\times 100 \right\}%\] But \[\left\{ \frac{x}{(100-x)}\times 100 \right\}%\] So, \[\frac{90x}{100}=9\] \[=\left\{ \left( \frac{r}{r-100} \right)\times 100 \right\}%\]You need to login to perform this action.
