B. 41.5

tbhauer · Answer

Average Price/kg = total monetary value / total number of kg
Total monetary value = (32 Rs/kg * 5 kg) + (50 Rs/kg * 7kg) = 160 Rs + 350 Rs = 510 Rs
Total number of kg = 5 + 7 = 12
Average Price/kg = 510/12 = 42.5 Rs/kg
Ans=C

Abhishek009 · Answer

\frac{32*5 + 50*7}{5+7}

=\frac{160 + 350}{12}

Solution

Given  
In this question, we are given that
 • Jim bought 5 kgs of rice costing Rs. 32 per kg and another 7 kgs of rice costing Rs. 50 per kg.

To find  
We need to determine
 • The average cost price per kg of rice Jim bought.

Approach and Working out  
Total price of first type of rice = 32 x 5 = 160
Total price of second type of rice = 50 x 7 = 350
 • Total price of all the rice bought = (160 + 350) = 510
• Total amount of rice bought = 5 + 7 = 12 kg

Hence, the average cost price per kg of rice bought = 510/12 = 42.50

Thus, option C is the correct answer.

Correct Answer: Option C

Jim bought 5 kgs of rice costing Rs. 32 per kg and another 7 kgs of ri
