Answer 1

- x + y + 3 =200 Number of shares 2+ y + 3 cortof shares = 164+564+803 = 11,600 Dividends (100) (803) > 0.076 +0.024+0.02% - 1.12x + 1.124 + 1.63=272 we need to solve for 214,2. by Gauseion elimination method (554) 272. x=50 y = 3 = 100 WSR= 50 sharee HCC 50 Shares SNDK 100 shares

21 22 23 - 200 1621-56.29 +8023 = 11600 1.12.0+ 1.12a + 1.623 = 272 Rewrite the system in matrix form and solve it by Gaussian Elimination (Gauss- Jordan elimination) 1 1 1 16 56 80 1.12 1.12 1.6 200 11600 272 R2 - 16 R1 - R2 (multiply 1 row by 16 and subtract it from 2 row); R3 - 1.12 R1 R3 (multiply 1 row by 1.12 and subtract it from 3 row) 0 0 1 1 200 40 64 8400 0 0.48 R2 / 40 R2 (divide the 2 row by 40) 1 1 1 0 1 1.6 0 0 0.48 200 210 48 R1 - 1 R2 R1 (multiply 2 row by 1 and subtract it from 1 row) 1 0 0.6 0 1 1.6 00 0.48 -10 210 48 R3 / 0.48 R3 (divide the 3 row by 0.48) 10 -0.6 -10 0 1 1.6 210 0 0 1 100 R1 + 0.6 R3 R1 (multiply 3 row by 0.6 and add it to 1 row); R2 - 1.6 R3 - R2 (multiply 3 row by 1.6 and subtract it from 2 row) 10 0 1 0 0 1 50 SO 100 21-50 250 33-100
