deduction u/s. 80P(2)(d

1. As per sec 80P(2)(d) it read as "in respect of any income by way of interest or dividend derived by the co-operative society from its investment with any other co-operative society, the whole of such income" 
2. Hence, from the above reading, we can say that any income earned by one Co-operative society by investing in another Co-operative society will be available as deductions under chapter VI-A deductions. 
3. In your case, the entire interest or dividend earned from the other Co-operative society will be available as a deduction. 
Please correct me if the above solution has an alternative view.
