A glass manufacturer produces transparent right prism blocks with a square base of side 10 cm and height 25 cm. If the selling price is ₹0.60 per cm³ and the cost price is ₹0.40 per cm³, what is the total profit earned on selling 12 such prisms?
Show answer & explanation
Correct answer: B
Explanation
Given:
Side of the square base = 10 cm
Height = 25 cm
Selling price = ₹0.60 per cm³
Cost price = ₹0.40 per cm³
Number of prisms = 12
Area of the base = 10² = 100
Volume = Base area × Height
Volume of one prism = 100 × 25 = 2500 cm³
Profit per cm³ = 0.60 − 0.40 = ₹0.20
Profit on one prism = 2500 × 0.20 = ₹500
Total profit on 12 prisms = 12 × 500 = ₹6000
