An L-shaped floor is made of two rectangles (6 m × 4 m) and (8 m × 6 m). Tiles cost ₹450/m2, but a 10% discount is given if more than 70 m2 is tiled. What is the total cost after the discount?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. ₹29,160.
Area of first rectangle = 6 × 4 = 24
Area of second rectangle = 8 × 6 = 48
Total area = 24 + 48 = 72 m2
Since > 70 ⇒ 10% discount
Cost before discount = 72 × 450 = 32400
Discount = 10% of 32400 = 3240
Final cost = 32400 − 3240 = ₹29160
