i. | 4500 | 5000 | ||
ii. | 4100 | 4090 | ||
iii. | 700 | 799 | ||
iv. | 1000 | 920 |
Solution:
i. Cost price = Rs 4500
Selling price = Rs 5000
Selling price is greater than cost price.
âˆ´ There is a profit.
âˆ´ Profit = Selling price â€“ Cost price
= 5000 â€“ 4500
Profit = Rs 500
ii. Cost price = Rs 4100
Selling price = Rs 4090
Cost price is greater than selling price.
âˆ´ There is a loss.
âˆ´ Loss = Cost price â€“ Selling price
= 4100 â€“ 4090
âˆ´ Loss = Rs 10
iii. Cost price = Rs 700
Selling price = Rs 799
Selling price is greater than cost price.
âˆ´ There is a profit.
âˆ´ Profit = Selling price â€“ Cost price
= 799 â€“ 700
âˆ´ Profit = Rs 99
iv. Cost price = Rs 1000
Selling price = Rs 920
Cost price is greater than selling price.
âˆ´ There is a loss.
âˆ´ Loss = Cost price â€“ Selling price
= 1000 â€“ 920
âˆ´ Loss = Rs 80
Ex. | Cost price (in Rs) | Selling price (in Rs) | Profit or Loss | How much? |
i. | 4500 | 5000 | Profit | Rs 500 |
ii. | 4100 | 4090 | Loss | Rs 10 |
iii. | 700 | 799 | Profit | Rs 99 |
iv. | 1000 | 920 | Loss | Rs 80 |

Question 5.
Pramod bought 100 bunches of methi greens for Rs 400. In a sudden downpour, 30 of the bunches on his handcart got spoil. He sold the rest at the rate of Rs 5 each. Did he make a profit or a loss? How much?
Solution:
Cost price of 100 bunches of methi green = Rs 400
Since, 30 bunches got spoil,
âˆ´ Remaining bunches of methi green = 100 â€“ 30 = 70
Selling price of 1 bunch of methi green = Rs 5
âˆ´ Selling price of 70 bunches of methi green = 5 x 70 = Rs 350
Cost price is greater than selling price
âˆ´ Pramod suffered a loss.
Loss = Cost price â€“ Selling price
= 400 â€“ 350
= Rs 50
âˆ´ Pramod suffered a loss of Rs 50.
Question 6.
Sharad bought one quintal of onions for Rs 2000. Later he sold them all at the rate of Rs 18 per kg. Did he make a profit or incur a loss? How much was it?
Solution:
Cost price of one quintal onions = Rs 2000
Selling price of 1 kg onions = Rs 18
Since, 1 quintal = 100 kg
âˆ´ Selling price of 1 quintal (100 kg) onions = 18 x 100 = Rs 1800
Cost price is greater than selling price
âˆ´ Sharad suffered a loss.
âˆ´ Loss = Cost price â€“ Selling price
= Rs 2000 â€“ Rs 1800
= Rs 200
âˆ´ Sharad incurred a loss of Rs 200.
Question 7.
Kantabai bought 25 saris from a wholesale merchant for Rs 10000 and sold them all at Rs 460 each. How much profit did Kantabai get in this transaction?
Solution:
Cost price of 25 saris = Rs 10000
Selling price of 1 sari = Rs 460
âˆ´ Selling price of 25 saris = 460 x 25 = Rs 11500
Selling price is greater than cost price.
âˆ´ Profit = Selling price â€“ Cost price
= 11500 â€“ 10000
= Rs 1500
âˆ´ Kantabai made a profit of Rs 1500.
