The table provided displays the estimated cost (in ₹ lakh) for the construction of a canal between two points.
Based on the information in the table, answer the questions that follow.
If the cost of materials increases by 5% each year from 2022 onwards, by how much with the estimated cost (in lakh ₹) rise.
First, let us note down the table and find out the sum of the costs across the rows and columns:
The cost of materials increases by 5% each year from 2022 onwards:
=> We need to consider the costs of Bolster, Brace, Slabs and the other materials.
=> The increase in over cost is 5% of [120 + 67.5 + 18 + 27 + 112.5 + 90 + 24 + 31.5] = 24.525 [close to option-D]
