M. P = Rs 2240
Discount % = 15%
Discount allowed =Rs 15100×2240=Rs 336
Thus, S.P. of the saree = Rs (2240 -336) = Rs 1904
Now, profit % of the shopkeeper = 19%
Therefore, C.P. =100×S.P(100+Profit percent)=Rs100×1904(100+19)=Rs 100×1904119
=Rs 100×16=Rs1600
Thus, the cost price of the saree is Rs 1,600.
