Each of the questions below consists of a question and three statemen...
From I
Let the cost price of the camera be ₹100
Marked price = ₹160
Equivalent discount = 10 + 15 - (10 x 15)/100 = 23.5%
Selling price = 160 x (100 - 23.5)/100 = 122.4
Profit = (122.4 - 100) = ₹22.4
For profit of ₹22.4 cost price is ₹100
Then, for a profit of ₹5376, cost price = (5376 x 100)/22.4 = ₹24000
Required selling price = (24000 x 112/100) = ₹26880
Hence, statement I alone is sufficient.
From II: Let the cost price of camera be ₹Y
Then,
Selling price for 20% profit = 1.2Y
Selling price for 28% profit = 1.28Y
Difference of selling price = ₹1440
1.28Y - 1.2Y = 1440
Y = ₹18000
Thus, required selling price = (18000 x 112/100) = ₹20160
Hence, statement II alone is sufficient.
From III: Let the cost price of the seller be ₹Y
Selling price of Seller is the same as the cost price for Raja.
Thus, Y x 110/100 x 145/100 x 80/100 = ₹22968
Y = (22968 x 100/110 x 100/145 x 100/80) = ₹18000
Thus, required selling price = (18000 x 112/100) = ₹20160
Hence, statement III alone is sufficient.
