Question

A shopkeeper sold a watch for Rs. 1440 at a profit of 20%. But he purchased it for Rs1000. Then the amount he spent on its repair ​

Answer 1

Answer:

Rs.200

Step-by-step explanation:

First take out the profit amt from the selling price to get the CP + Repair amt:

=> $1440 * \frac{100}{120}$ = Rs. 1200

Therefore, 1440 - 1200 = Rs. 240 is the profit earned

Let repair amt. be x

CP + x = SP without Profit

1000 + x = 1200 --------------->(1440-240)

x = 1200 - 1000

x = 200

Let's Check:

• CP + Repair = Selling Price without Profit

        =>  1000 + 200 = Rs. 1200

• Selling Price without Profit + 20% Profit = Selling Price

         =>  1200 + 20%

         =>  1200 + ($1200 * \frac{20}{100}$)

         => 1200 + 240  = Rs. 1440
