1. Total deductions available u/s 80C is Rs. 1,50,000. However, contribution to NPS scheme is covered u/s 80CCD(1B). This contribution is over and above Rs.1,50,000 above. Maximum deductions available under this section would be Rs. 50,000.
2. Hence in your case Rs. 50,000 u/s 80CCD(1B) and balance of Rs. 13,000 will be added to sec 80C and the total deductions u/s 80C is Rs. 133,000.
Please correct me if the above solution has an alternative view.
