Question

Ted’s uncle wants to put tiles on his home floor. The total area of the floor to be tiled is 360000 square cms. Find the cost of tiling at ₹ 20 per square metre.

• A. ₹ 360
• B. ₹ 3600
• C. ₹ 720
• D. ₹ 7200

Answer 1

The correct option is C

₹ 720

100 cm = 1 m

10000 $c{m}^2$ = 1 $m^2$

Area of floor to be tiled = 360000 $c{m}^2$

= (360000/10000) $m^2$

= 36 $m^2$

So, cost of tiling the floor = 20 $\times$ 36 = ₹ 720
