Question 126

what is the average price per kg. of wheat and rice sold ? (rounded off to nearest integer)

Solution

For wheat :

Total quantity sold = 750 kg and price per kg = Rs. 25

=> Total cost = 750 * 25 = Rs. 18,750

For rice :

Total quantity sold = 600 kg and price per kg = Rs. 45

=> Total cost = 600 * 45 = Rs. 27,000

$$\therefore$$ Average price per kg. of wheat and rice sold

= $$\frac{18750 + 27000}{750 + 600}$$

= $$\frac{45750}{1350} = 33.89 \approx 34$$
