Question

The price of an article decreased twice successively, first by $30\%$ and then by $40\%$. If the original price was Rs.1000, what is it now?

• A. Rs. 400
• B. Rs. 300
• C. Rs. 240
• D. Rs. 420

Answer 1

The correct option is D

Rs. 420

Original price of the article = Rs.1000

Price of the article after $30\%$ decrease = $1000-\frac{30}{100}\times 1000$ = $Rs.700$

Price of the article after $40\%$ decrease = $700-\frac{40}{100}\times 700$ = $Rs.420$
