Let the cost price (CP) be ( x ) Rs.
The profit is given as 10%, so the profit amount is $0.10 \times x$ .
The difference between the selling price (SP) and the cost price is Rs. 120.

So, we can write the equation: SP – CP = 120

Since profit is 10%, we have: $SP = CP + 0.10 \times CP$ , $SP = 1.10 \times CP$

Given: SP – CP = 120
$1.10 \times CP - CP = 120$
$0.10 \times CP = 120$
$CP = \frac{120}{0.10}$
CP = 1200

Now, the selling price (SP) is: $SP = 1.10 \times 1200$
SP = Rs 1320

So, the selling price is Rs. 1320.
