| A man sold his watch at a loss of 5%. Had he sold it for Rs. 56.25 more, he would have gained 10%. What is the cost price of the watch (in Rs.)? [SSC (10+2) 2014] |
A) 370
B) 365
C) 375
D) 390
Correct Answer: C
Solution :
| Let CP of the watch be Rs. x. |
| According to the question, |
| \[\frac{x\times (100+10)}{100}-\frac{x\times (100-5)}{100}=56.25\] |
| \[\Rightarrow \] \[\frac{110x}{100}-\frac{95x}{100}=56.25\]\[\Rightarrow \]\[\frac{15x}{100}=56.25\] |
| \[\Rightarrow \] \[x=\frac{56.25\times 100}{15}=\frac{5625}{15}\] |
| \[\Rightarrow \] \[x=Rs.\,375\] |
