2017 · 9 Apr · Shift 1 · Q27

JEE MainMathematicsMatrices and DeterminantsMCQ+4 / −1
For two 3 × 3 matrices A and B, let A + B = 2BT and 3A + 2B = I3, where BT is the transpose of B and I3 is 3 × 3 identity matrix. Then :
  1. A
    5A + 10B = 2I3
  2. B
    10A + 5B = 3I3
  3. C
    B + 2A = I3
  4. D
    3A + 6B = 2I3
