Given:
Quantity of Rice 1 = 30 kg
Cost of Rice 1 = Unknown (Let's call it 'x' ₹/kg)
Quantity of Rice 2 = 60 kg
Cost of Rice 2 = ₹100/kg
Cost of Mixture = ₹110/kg
Formula Used:

Total cost of Rice 1 = 30 kg x ₹/kg = 30x ₹
Total cost of Rice 2 = 60 kg₹100/kg = ₹6000
Total quantity = 30 kg + 60 kg = 90 kg
₹110/kg =
110 90 = 30x + 6000
9900 = 30x + 6000
3900 = 30x
x =
x = ₹130/kg
Therefore, the cost of the first type of rice is ₹130 per kg.
