If Mr. A is a resident in India for AY 2013-14, then, i need to know as to what rate of conversion needs to be used for salary earned in USD ($) in the month of April, MAy and June and for Tax paid therein. I  need this for the purpose of calculating the tax payable for AY 13-14 and for deducting the tax paid in US thereon. Are there any other tax benefits available?
