Question 1.

Maganlal bought trousers for Rs 400 and a shirt for Rs 200 and sold them for Rs 448 and Rs 250 respectively. Which of these transactions was more profitable?

Solution:

Cost price of trousers = Rs 400

Selling price of trousers = Rs 448

Profit = Selling price – Cost price

= 448 – 400 = Rs 48

Let Maganlal make x % profit on selling trousers

∴ x = 12%

Cost price of shirt = Rs 200

Selling price of shirt = Rs 250

∴ Profit = Selling price – Cost price

= 250 – 200

= Rs 50

Let Maganlal make y% profit on selling shirt.

∴ y = 25%

∴ Transaction involving selling of shirt was more profitable.

Question 2.

Ramrao bought a cupboard for Rs 4500 and sold it for Rs 4950. Shamrao bought a sewing machine for Rs 3500 and sold it for Rs 3920. Whose transaction was more profitable?

Solution:

Cost price of cupboard = Rs 4500

Selling price of cupboard = Rs 4950

∴ Profit = Selling price – Cost price

= 4950 – 4500

= Rs 450

Let Ramrao make x% profit on selling cupboard

∴ x = 10%

Cost price of sewing machine = Rs 3500

Selling price of sewing machine = Rs 3920

∴Profit = Selling price – Cost price

= 3920 – 3500

= Rs 420

Shamrao make y% profit on selling sewing machine.

∴y = 12%

∴Shamrao’s transaction was more profitable.

Question 3.

Hanif bought one box of 50 apples for Rs 400. He sold all the apples at the rate of Rs 10 each. Was there a profit or loss? What was its percentage?

Solution:

Cost price of 50 apples = Rs 400

Selling price of one apple = Rs 10

∴ Selling price of 50 apples = 10 x 50 = Rs 500

Selling price is greater than the total cost price.

∴ Hanif made a profit.

∴ Profit = Selling price – Cost price

= 500 – 400

= Rs 100

Let Hanif make of x% profit on selling apples.

∴ x = 25%

∴ Hanif made a profit of 25%.
