XYZ mixes 64 kg of rice worth Rs.85 per kg with 36 kg of rice worth Rs.105 per kg. At what rate should he sell the mixture to gain 10%? (In Rs.)

Correct option is D

Cost of first rice
= 64 × 85
= 5440

Cost of second rice
= 36 × 105
= 3780

Total cost
= 5440 + 3780
= 9220

Total quantity
= 64 + 36
= 100 kg

Cost per kg
= 9220 / 100
= 92.2

Selling price with 10% gain
= 92.2 × 1.10
= 101.42
