@Fayaz02 The charges of jeep vary, I mentioned about Suzuki Potohar that charged 3,000 (round trip with stay at hill on night and return on the next morning). Bigger jeep would have different charges. Also, perhaps better negotiation would have made a difference in your case.
Food at Gorakh was excellent, though a little expensive, but that's understandable that they need to bring the stuff to that hill so naturally they would charge you more. The room rent was Rs. 3,000/- per night.
On google maps, if you read further, I have written the same thing, that if in doubt it is better to ask a local person. The reason google fails sometimes is, in my opinion, because google imagery is 10-12 months old and they might not have updated the current changes on small roads. For highways, I guess, google is very reliable.
