Question

3. By selling a shirt for 2520, a shopkeeper earns
a profit of 5%. At what price should he sell it to
earn a profit of 18%?​

Answer 1

Answer:

The shirt must be sold in ₹427.56 to gain 18% profit.

Step-by-step explanation:

S. P. of the shirt is ₹2,520 if it is sold in 5% profit

Let the C. P. be ₹x

Then S. P. will be

x + x of 5% = 21x/20

A/q,

$\sf : \implies \: \frac{21x}{20} = 2520 \\ \sf : \implies \: x = \frac{2520 \times 20}{21} \\ \sf : \implies \: x = 210 \times 20 \\ \sf : \implies \: x = 420$

Now, We are getting the C. P. ₹420

Again to be sold on 18% profit :-

So,

= 420 + 420 of 18%

= 420 + 75.6

= ₹427.56
