Tax on uk salary (resident indian)

Hi,
I am going to stay for less than 183 days in UK & earn UK salary. Taxes are deducted from Salary in UK. No salary is earned in India for this period.

Q: Since I will have to pay tax in india on my total income (India + UK), would personal allowances paid in UK (£10,600/annum and considered tax free) be also to be included as taxable income in India?

If ans to above Q. is yes, how does Indian tax authorities balance of the difference in cost of living between India & other contries? I mean, how does the allowable deductions of India suffice for someone who has to stay in other country where there is huge difference in cost of living?

Regards,
NP
