When an article is sold at 20% discount, the selling price is Rs 24. What will be the selling price when the discount is 30%? (

A) Rs.25
B) Rs.23
C) Rs.21
D) Rs.20

Correct Answer:



C) Rs.21

Description for Correct answer:
Let the C.P. of article be Rs. 100

Now discount of 20% is given on C.P

SP = Rs. 80

Now here SP = Rs. 24

C.P. of an article = Rs \( \Large \left(\frac{24 \times 100}{80} \right) \) = Rs. 30

Now 30% discount is given original C.P. of an article

SP of article = Rs.(30 -9) = Rs 21
