Solution

The correct option is C
₹ 2250

Given: Length of the locker, $l = 50 c m$

Breadth, $b = 50 c m$

Height, $h = 2 m = 200 c m$

Total surface area of the cuboidal locker $= 2 (l b + b h + l h) = 2 (50 \times 50 + 50 \times 200 + 50 \times 200) = 2 \times 22500 = 45000 c m^{2}$

Cost of installing a touch sensor system $=$ ₹ 5 per 100 sq. cm

So, total cost to be incurred $=$ ₹ $\frac{5}{100} \times 45000 =$ ₹ $2250$
