The standard workday of a Indian is 9 hours, and this guy is demanding 10 hours of work.
Next, 6/10$ = assuming current exchange rate being 66 INR/USD the rate is close to 36 INR p/h.
India's poverty rate World Bank's income-based poverty rate is 1.25$.
Now, this is very low and I'd see this as a wastage of time.
India.In US dollar terms it is $4.13 per day.Op is offering much more than this

Please, wages depend on the skill.
As many would notice, doing captcha is a mental work and not a labour work, please go to that above page and read it yourself.
In India, standard workday is 9 hours or 8 hours.
So, this wouldn't require much skill.
Next: the low skill wage is what? 11400.00 INR p/m.
If we assume 4 days for Sunday, zero holidays then...
The hourly wage becomes:
11400/26(assuming this month is a 30-day month)/8(the work time), that becomes 54 INR, and the wage is what? 36 INR p/h.
that is about 150% increase.
