Question

13. A grain wholesaler earns a profit of 12 per bag of wheat sold and a loss
of 8 per bag of rice sold.
i. If he sells 1500 bags of wheat and 2050 bags of rice in a month, what is his profit or loss?
What is the number of wheat bags he must sell to have neither profit nor loss, if the numb
of rice bags sold is 2400 bags?​

Answer 1

1. find cost of wheat 12×1500=18000

then find cost of rice = 2050×8=16400

we will denote cost of rice by a negative sign because it is loss as per question

then to find profit or loss = 18000+(-16400)

=18000-16400

= the profit of ₹1600

2. let the number of wheat bags sold = X

profit= loss

X × 12= 2400×8

X × 12= 19200

X = 19200÷12

X = 1600

Answer 2

1. The cost of wheat = 1500 × 12

= 18000

The cost of rice = 2050 × 8

= 16400

profit or loss = 18000 + (-16400)

the profit of = 16400
