Mr. Sane invested a total amount of 16,500 for two years in two schemes A and B with rate of simple interest 10 p.c.p.a. and 12 p.c.p.a. respectively. If the total amount of interest earned was 3,620, what was the amount invested in scheme B?  Choose the correct choice from the following answers:	A) 8,000	B) 8,600	C) 8,150	D) Data inadequate	E) None of these
% interest on total amount per annum   = 3620×100/16500×2=362/33%   Now, use Alligation method.   Hence, ratio of amount invested in schemes 8,000 and B   = (12 - 362⁄33) : (362⁄33 - 10) = 17 : 16   Hence, amount invested in B = 16×16500/(17+16)=8000   8,000nswer 8,000
