A) Rs. 275
B) Rs. 250
C) Rs. 225
D) Rs. 220
Correct Answer: C
Solution :
CP of watch = Rs. x \[\therefore \] On 5% loss, \[SP=\frac{(100-5)}{100}x=\]Rs. \[\frac{19}{20}x\] Given, \[\frac{19}{20}x+27=\]Rs. \[\frac{(100+7)}{100}x\] \[\Rightarrow \] \[\frac{107}{100}x-\frac{19}{20}x=\]Rs. \[\Rightarrow \] \[\frac{(107-95)}{100}x=27\] \[\therefore \,\] \[x=27\times \frac{25}{3}=225\]You need to login to perform this action.
