Interest acquired by means of A from B = 10% of half of of Rs.50000 = 10% * 25000 = 2500.

Amount obtained with the aid of A per annum for being a operating accomplice = 1500 * 12 = Rs.18000.

Let 'P' be the part of the closing income that A receives as his percentage. Total profits of A = (2500 + 18000 + P)

Total income of B = only his percentage from the ultimate earnings = 'P', as A and B proportion the final income equally.

Income of A = Twice the income of B

(2500 + 18000 + P) = 2(P)

P = 20500

Total income = 2P + 18000

= 2*20500 + 18000 = 59000.
