The list price of an electric fan is Rs. 300. If two successive

The list price of an electric fan is Rs. 300. If two successive discounts of 15% and 10% are
allowed, its selling price would be

Single equivalent discount for 15% and 10%. =		15 + 10 −	15 × 10		%
			100

Single equivalent discount for 15% and 10%. = (25 – 1.5) % = 23.5 %
∴ Required S.P = (100 – 23.5)% of 300

∴ Required S.P =	300 × 76.5	= Rs. 229.5
	100

2nd Method to solve this question :
According to given question.
Here, M.P. = Rs. 300, S.P. = ?
D₁ = 15%, D₂ = 10%

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

S.P = 300		100 − 15			100 − 10
		100			100

S.P = 300 ×	85	×	90	= 229.50
	100		100
