2. The table below shows the estimated cost (in Rs. Lakh) of a project of laying a railway line between two places. 1) The total expenditure is required to be kept within Rs. 700 lakh by cutting th administration equally in all the years. What will be the percentage cut for 1989? e expenditure on 1989 7.5 95.0 70.0 15.0 25.0 1990 2.2 80.0 45.0 12.0 18.0 1991 0.5 75.0 60.0 16.0 21.0 1988 1. Surveying 2. Cement 3. Steel 4.

4. The table below shows the estimated cost (in Rs. Lakh) of a project of laying a railway line between two places. 5) It is found at the end of 1990, that the entire amount estimated for the project has been spent.
