Question of The Day31-05-2021

By selling an article for ₹2520 a man allows the successive discount of 20% and 25% and earns a profit of 10%. If the article is sold at 0% discount, what would be the profit?

Correct Answer : c ) 83.33%

Explanation :

According to the question

Profit percentage = 10%

The man allows the discount of 20% and 25%

Single equivalent discount of 20% and 25%

We know that

$$x+y- {{x*y} \over 100}$$

Where x and y are the discount

$$20+25-{{20*25} \over 100}$$

⇒ 40%

We know that

$${MP \over CP}={{100+Profit} \over {100-Discount}}$$

$${MP \over CP}={{100+10} \over {100-40}}$$

$${MP \over CP}={{110} \over {60}}={{11} \over {6}}$$

If the discount is not given, then the article is sold at the marked price

MP = SP

$$Profit \ Percentage={5 \over 6}*100$$

⇒ 83.33%

Hence, (c) is the correct answer.
