A mason was told to build a wall with base 9 m and height 12 m. The cost of building the wall is Rs 100 per sq m. He built the base of 9 m, but after building the wall, it was found that the height on one side is 12 m and on the other 13 m, so the top was measured and found to be 14 m instead of 9 m. Find the increase in the cost of building the wall.
