A) \[23\frac{3}{4}\]
B) 22
C) \[21\frac{7}{8}\]
D) 30
Correct Answer: C
Solution :
[c] Let CP = Rs. x Then, MP = 130% of x = Rs. 1.3x \[\therefore \] \[SP=1.3x\times \left( 100-\frac{25}{4} \right)%\] \[=1.3x\times \frac{375}{400}=\text{Rs}.\frac{15}{16}\times 1.3x\] \[\therefore \] Gain per cent \[=\frac{\frac{15}{16}\times 1.3x-x}{x}\times 100\] \[=\frac{(19.5-16)x}{16x}\times 100=21\frac{7}{8}%\] |
