(a)
Quantity A :Suppose the cost price of 1000 gm goods is Rs. 1000;
Since he sells the goods at 5% profit ;
∴ Selling price of 1000 gm goods = Rs. 1050
But he uses 10% less weight that means he gives 900
gm goods for ₹1050;
∴ Actual selling price of 1000 gm goods
=(9001050​)×1000=Rs. 1166.67 ∴Actual profit earned by the Ramu
=
[10001166.67−1000​]×100=16.67% Quantity B : Since Rohit sells 64 oranges for Rs. 2
∴ Selling price of 1 orange = Rs.
642​=321​ He suffers a loss of 40%
∴Cost price of 1 orange = (1/32) / 0.6 = Rs. (1/19.2)
Selling price of 1 orange for earning 20% profit
=(19.21​)×1.2=₹ 161​ ∴He should sell 16 oranges for ₹1 to earn 20% profit.
∴ Quantity A > Quantity B
