Question 129

If the quantities sold of Groundnut and Cumin are interchanged, what will be the total cost of quantities sold for these two items together ?

Solution

Quantity sold for groundnut and cumin are respectively 500 kg and 400 kg

After interchanging, quantity sold for groundnut = 400 kg

and quantity sold for cumin = 500 kg

Also, price per kg for groundnut = Rs. 60

and price per kg for cumin = Rs. 80

$$\therefore$$ Total cost of quantities sold for these two items together

= Rs. $$(400 \times 60 + 500 \times 80)$$

= Rs. $$(24,000 + 40,000)$$

= Rs. $$64,000$$
