Two persons A and B started a business with initial investments of Rs. 2,000 and Rs. 3,000 respectively. A invested Rs. 1,000 additionally after every 4 months, and B invested Rs. 1,000 additionally after every 6 months. At the end of the year, A and B separated their profit s after deducting Rs. x for charity. If the total amount distributed between them is Rs. 26,000, and the total share given to A (including the charity amount deducted from his share proportionally) results in A receiving a net profit share of Rs. 12,000 from the distributed amount, find the value of x (knowing that total profit before charity was Rs. 32,500).
