(Chris) I though I would post some typical costs we've seen or encountered here in India so far on our trip...
gasoline (petrol): 50 rupees per/litre = $1.13 Cdn
1 litre bottled water (ex. Aquafina): 15-30 rs = $.34 cents - $.68 cents Cdn
bottle of Coke or other soft drinks: same as water
taxi/auto rickshaw: avg 50-100 rs per trip = $1.13 to $2.26 Cdn (so cheap compared to getting around a city in Canada!)
avg meal: 200-300 rs = $4.50 - $7.00 Cdn
chocolate bar: 15- 30 rs = $.34 to $.68 cents Cdn
internet use: 15-20 rs per half hour = $.34 - $.45 cents Cdn
tailored pants & shirt: 1600 rs = $36 Cdn
paperback novel: 250 rs = $5.65 Cdn
3 star hotel (decent): 1500-2500 rs per night = $34 - $56 Cdn for 2 people
if anyone is wondering about any other costs let me know and I'll get back to you!
