Question

$5$% more is gained by selling a watch for $Rs.350$ than by selling it for $Rs.340$. The cost price of the watch is

• A. $Rs.110$
• B. $Rs.140$
• C. $Rs.200$
• D. $Rs.250$

Answer 1

Answer: (C)

$Rs.200$

Let cost price be $Rs.x$
Then $5$% of $x=(350-340)$
$5$% of $x=10$
$x=10\times \frac{100}{5}=200$
Hence, cost price is $Rs.200$.
