Question 127

If cumin is sold at a 10% discount, the quantity sold doubles. What will be the cost of total quantity of cumin sold on discount ?

Solution

Total quantity of cumin sold = 400 kg and price per kg = Rs. 80

Now, after 10 % discount, price = $$80 - \frac{10}{100} \times 80$$ = Rs. $$72$$

New quantity sold for cumin = $$2 \times 400 = 800$$ kg

$$\therefore$$ Total quantity of cumin sold on discount

= Rs. $$(800 \times 72)$$

= Rs. $$57,600$$
