Question

The price of an article diminished twice successively, first by $30\%$ and then by $40\%$. 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. $420$

Successive discounts of $30\%$ and $40\%$ are given on an article

Final price $=1000\times \frac{(100-30)}{100}\times \frac{(100-40)}{100}$

$=1000\times \frac{70\times 60}{10000}$

$=$ Rs. $420$
