Question

11. A seller earned 20% profit by selling a wall-clock for Rs. 250. In what
price the purchaser should sell it to get a profit of 20%?
(a) Rs. 300 (b) Rs. 280 (c) Rs. 320 (d) None of these​

Answer 1

Step-by-step explanation:

sp = cp(1+g%)

250 = cp(1+20%) = cp(1+.2) = 1.2cp

cp = 250/1.2 = 208.33

profit = 20%

sp = 250

Answer 2

Therefore the selling price of the wall clock must be Rs. 300/- to get a 20% profit. ( Option-a )

Given:

Profit earned by selling a wall clock by the seller = 20%

Cost Price of the wall clock by the purchaser = CP = Rs. 250

The profit that should be earned by the purchaser = 20%

To Find:

The selling price of the wall clock to obtain 20% profit.

Solution:

The given question can be solved as shown below.

Let the Selling price of the wall clock be 'SP' to get 20% of the profit.

Given that,
Cost Price of the wall clock by the purchaser = CP = Rs. 250

The profit that should be earned by the purchaser = 20%

Profit percentage = [ ( SP - CP )/CP ] × 100

⇒ 20 = [ ( SP - 250 )/250 ] × 100

⇒ 0.2 × 250 = SP - 250

⇒ SP = 250 + 50 = 300

Therefore the selling price of the wall clock must be Rs. 300/- to get a 20% profit.
