The income aspect is the one which causes hurdle to your proposed application.
However as per the rule which was clarified in para 7 of Department of Personnel and Training O.M. No.36033/5/2004-Estt.(SCT), dated the October, 2004, to all Ministries/Departments, etc. which is reproduced below, it is clear that you are very much eligible:
7. In regard to clause (v) of para 4, it is clarified that the sons and daughters of parents of whom only the husband is a directly recruited Class II/Group B officer who gets into Class I/Group A at the age of 40 or earlier are treated to be in creamy layer. If the father is directly recruited Class III/Group C or Class IV/Group D employee and he gets into Class I/Group A at the age of 40 or earlier, his sons and daughters shall not be treated to be falling in creamy layer.
I have reproduced the income computation for eligibility herein below:
The creamy layer status of sons and daughters of persons employed in organizations where equivalence or comparability of posts vis-à-vis posts in Government has not been evaluated is determined as follows:
“Income of the parents from the salaries and from the other sources [other than salaries and agricultural land] is determined separately. If either the income of the parents from the salaries or the income of the parents from other sources [other than salaries and agricultural land] exceeds the limit of Rs.6 lakh per annum for a period of three consecutive years, the sons and daughters of such persons shall be treated to fall in creamy layer. But the sons and daughters of parents whose income from salaries is less than Rs. 6 lakh per annum and income from other sources is also less than Rs.6 lakh per annum will not be treated as falling in creamy layer even if the sum of the income from salaries and the income from the other sources is more than Rs.6 lakh per annum for a period
of three consecutive years. It may be noted that income from agricultural land is not taken into account while applying the Test.”
Note: While applying the Income/Wealth Test to determine creamy layer status of any candidate as given in Category-VI, income from the salaries and income from the agricultural land shall not be taken into account. It means that if income from salaries of the parents of any candidate is more than Rs. 6 lakh per annum, income from agricultural land is more than Rs.6 lakh per annum, but income from sources other than salaries and agriculture is less than Rs. 6 lakh per annum, the candidate shall not be treated to be falling in creamy layer on the basis of Income/Wealth Test provided his parent(s) do not possess wealth above the exemption limit as prescribed in the Wealth Tax Act for a period of three consecutive years.
Now you decide what can be done on it.
