CAT 2021 Geometry & Mensuration Question (Medium)

Question

A roller is 4 m long and has a diameter of 0.7 m. It takes exactly 2000 rotations of the roller to level a road. If the cost of using the roller is Rs. 4 per square metres, then the total cost of levelling the road is Assume 22 7

Optima Learn · Accepted Answer

To find the total cost, we need to compute the area covered per rotation, then scale by the number of rotations and the cost rate. Understanding the setup the roller has length 4 m and diameter 0.7 m radius 0.35 m , making 2000 rotations, at a cost of Rs. 4 per square metre. Analyzing the Calculatio
