Solution : Gain% = 10% The selling price of the mixture = INR 55 Amount of rice costing INR 45 per kg = 35 kg Let the quantity of rice costing Rs. 42 per kg be $x$ kg The cost price of the mixture = Rs. $\frac{55}{110}$ × 100 = Rs. 50 per kg Equating cost price of mixture weighing (x + 35) kg, 50 × ($x$ + 35) = 52 × $x$ + 35 × 45 ⇒ 35 × 5 = 2$x$ ⇒ $x$ = 87.5 kg Hence, the correct answer is 87.5 kg.
