A chair listed at ₹ 350 is available at successive discounts

A chair listed at ₹ 350 is available at successive discounts of 25% and 10%. The selling price of the chair is

Single equivalent discount =		25 + 10 −	25 × 10		= 32.5%
			100

∴ S.P. of chair =	350 (100 − 32.5)
	100

∴ S.P. of chair =	350 × 67.5	= ₹ 236.25
	100

Alternate method to solve this question :
Here, M.P. = 350, D₁ = 25 %, D₂ = 10 %

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

S.P = 350 ×		100 − 25			100 − 10
		100			100

S. P = 350 ×	75	×	90	= ₹ 236.25
