Answer 1

The profit of the shopkeeper is 261.33 Rs.

Step-by-step explanation:

Let the cost price be x Rs.

Then marking 20% above the cost price means the marked price x(1 + \frac{20}{100}) = 1.2xx(1+10020)=1.2x .

Again, giving 5% discount on the marked price then selling price becomes

1.2x(1 - \frac{5}{100}) = 1.14x1.2x(1−1005)=1.14x

Now, given that 1.14x = 2128

⇒ x = 1866.67 Rs.

So, the profit of the shopkeeper is (2128 - 1866.67) = 261.33 Rs. (Answer)
