\r\n Solution\r\n
Let x be the amount invested in scheme A and y be amount invested in amount invested in scheme B.
\r\nx+y = 16,000
\r\n(x(1+.1)^2 - x) + y*2*0.12 = 3504
\r\n0.21x + 0.24y = 3504
\r\nSolving the above equation we get,
\r\nx = 11,200
\r\ny = 4800
\r\nHe invested Rs.4800 in scheme B.
