A door-frame off dimensions 3 m × 2 m easy fixed on the wall of dimension 10 m × 10 m . Find the total labour charges for painting the wall if the labour charges for painting 1 m² of the wall is ₹ 2.50 .
Painting of the wall has to be done excluding the area of the door .
Area of the door = length × breadth
= 3 × 2 m²
= 6 m²
Area of wall including door = side × side
= 10 m × 10 m
= 100 m²
Area of wall excluding door = ( 100 — 6 ) m²
= 94 m²
Total labour charges for painting the wall = ₹ 2.50 × 95 = ₹ 235 .
