I totally agree with Dhirajlal Sir.
@ Jayesh Thakkar & @ Karthik,
If one could u/s 44ADA report profits of only 50% of gross receipts, when actuals were 70%, dont you think this would open up the gates for tax-evasion to the extent of this 20%. Eventhough not easy, all one would have to do in that case, was find a couple of people for partners and float a few firms, plan accordingly so that this 20% of 'TAX FREE' receipts could be increase manifold.
When a provision can be viewed from 2 different angles, then there can only be 'interpretations', until the Courts step in to cement a single view.
However, for now, what we can do, is apply the Rule of Harmonius Interpretation. The intention of the lawmakers in bringing section 44AD into effect, was to exempt the small businesses/professionals from maintaining books of accounts. They never intended make any leeway for assessees to make some windfall tax-evasions by reporting lesser than actual income.
Besides, even the advanced material hosted on INCOMETAXINDIA.gov.in states that actuals should be disclosed wherever it exceeds 8% or 50% as the case may be.

Besides, if the Department finds that there has been a serious evasions u/s 44AD, then it can rain down a barrage of penalties on you u/s 271(1)(c), 270A,etc so as to keep you skipping through courts for the next half decade.
Tax evasion has never been the intention of any of the sections of Income tax act. Literal Interpretations are very easy to make, and through experience, one may learn that being practical always pays off better.
