Correct Answer: Rs. 1000
Solution :
We know,
Equivalent single discount = $(a+b–\frac{a×b}{100}$)%,
where $a,b$ are successive discount.
So, $30+20-\frac{30\times 20}{100}=44$%
Selling Price of the article = Rs. 560
Marked price of the article = $S.P \times (\frac{100}{100-Discount\%})$
= $560 \times (\frac{100}{100-44})$
= $560 \times (\frac{100}{56})$
= Rs. 1000
Hence, the correct answer is Rs. 1000.
