Solution : The length of the cuboidal room = 80 m The breadth of the cuboidal room = 70 m The height of the cuboidal room = 80 m Cost of painting per square metre = 50 paise Area of four walls of cuboid = 2 × (Length + Breadth) × Height = 2 × (80 + 70) × 80 m$^2$ = 2 × 150 × 80 = 24000 m$^2$ Total cost of painting four walls of room = Rs. (24000 × $\frac{50}{100}$) = INR 12,000 Hence, the correct answer is INR 12,000.
