Allowing 20 % and 15 % successive discounts, the selling

Allowing 20 % and 15 % successive discounts, the selling price of an article becomes Rs. 3,060; then the marked price will be

Let us assume the Marked price of article = Rs. M
According to the question,

M ×	80	×	85	= 3060
	100		100

⇒ M =	3060 × 100 × 100
	80 × 85

M = Rs. 4500
Alternate method to solve this question :
According to given question.
Here, S.P. = Rs. 3060, M.P. = ?, D₁ = 20%, D₂ = 15%

S.P = M.P		100 − D₁			100 − D₂
		100			100

3060 = M.P.		100 − 20			100 − 15
		100			100

3060 = M.P.		80	×	85
		100		100

M.P. =	3060 × 10000
	80 × 85

M.P. = Rs. 4500
