Solution

Cost PER square metre,

Rate of painting = 3200

Rate of tiling = $\frac{125}{100} * 3200$ = 4000

Rate of carpeting = $\frac{120}{100} * 4000$ = 4800

Rate of DECORATING = 14 * 4800 = 67200

Area of tiles on the walls = 2 * 0.25 * (6 + 6) = 6 sq. metre

Area of the floor = 6 * 6 = 36 sq. metre

Cost of decorating = 36 * 67200 = Rs. 2419200

Cost of tiling = (36 + 6) * 4000 = Rs. 168000

$\therefore$ Total cost = 2419200 + 168000 = Rs. 2587200
