If I'm reading it right, the road is costing the
contractor Rs 20000, and is asking
+20000+%2B+.3%2A20000+=+26000+
-----------------
I'm assuming that the contractor must
stand by the quote, so only the cost changes.
Cost = +20000+%2B+.04%2A20000+=+20800+
---------------
The fraction of the gain is:
+%28+26000+-+20800+%29+%2F+20800+=+5200+%2F+20800+
The % gain is:
+%28+5200+%2F+20800+%29%2A100+
+.25%2A100+ = 25%
