Let the height of the wall = h = length of the ladder
When it is placed on a stool of 2 ft height, base of the ladder is 10 ft away from the wall.
So a right-angled triangle is formed with hypotenuse = h, base = 10 and height = (h - 2)
--> \(h^2 = (h - 2)^2 + 10^2\)
--> \(h^2 = h^2 - 4h + 4 + 100\)
--> \(4h = 104\)
--> \(h = 26\)
Height of the wall = h = 26
IMO Option B
