First, we have to calculate total cost of products separately.
1. Wheat- 1.50X10= 15 Rupees
2. Fuel- 0.50X20= 10 Rupees
3. Sugar- 2.80X5=14 Rupees
4. Oil- 10X2= 20 Rupees
Now, calculating arithmetic average,
= Sum of Total price of all products
Number of products
= 15+10+14+20/4
= 59/4
= 14.75
Answer: The weighted arithmetic average of the prices is 14.75.
