A) Rs. 130
B) Rs. 140
C) Rs. 150
D) Rs. 160
Correct Answer: C
Solution :
Let the CP of the book be Rs. x Initial SP \[=\frac{110}{100}\times x\]=Rs. 1.1 x New CP = Rs. 0.96 x New SP \[=\left( 100+\frac{75}{4} \right)%\]of Rs. 0.96 x \[=\frac{475}{400}\times 0.96x\]= Rs. 1.14 x Therefore, \[1.14x-1.1x=6\] \[\Rightarrow \] 0.04 x =6 \[\Rightarrow \] \[x=\frac{6}{0.04}=\frac{600}{4}=150\] \[\Rightarrow \] CP = Rs. 150You need to login to perform this action.
