Hi friend,
Cost of 1 kg of type 1 rice is ₹15
Cost of 1 kg of type 2 rice is ₹20
Type 1 and Type 2 are mixed in the ratio of 2 : 3
Type 1 quantity is 2 kg,then it's cost is 15×2=₹30
Type 2 quantity is 3 kg,then it's cost is 20×3=₹60
Quantity of mixed variety of rice = 2+3=5 kg
Therefore, the cost of mixed variety of rice = ₹30+₹60 = ₹90
So, 5 kg costs ₹90
Then 1 kg costs ?
=90/5
=₹18
Hope it helps
