• A. Rs. $1254$
• B. Rs. $1260$
• C. Rs. $1197$
• D. Rs. $1311$

Answer 1

The correct option is B Rs. $1260$

SP of watch $=1140$, Loss %$=5$%
$CP=\frac{100}{95}\times 1140[\because CP=\left(\frac{100}{100-Lpercent}\right)SP]$
SP at $5$% gain $=\frac{105}{100}\times \frac{100}{95}\times 1140=Rs.1260$
