An item costing Rs. 840 was sold by a shopkeeper at a gain of 10% and it was again sold by the new buyer at a loss of 5%.The final selling price of the item is:
C.P. = Rs. 840
Gain =10%
S.P. =100+gain percentage100× C.P
S.P. =100+10100×840
⇒110100×840= Rs. 924
Selling price of the shopkeeper is the cost price of the new buyer.
Then C.P. = Rs. 924
Loss =5%
S.P. =100−loss percentage100× C.P.
S.P =100−5100×924
⇒95100×924= Rs. 877.80
Hence, final S.P.=Rs. 877.80
