Section I consists of multiple correct answers type questions.
Section II consists of Integer type questions and
Section III consists of matching type questions.
Q. Which of the following is(are) not the square of a 3 × 3 matrix with real entries?
Sol. If the determinant of a matrix is positive then it can be represented as square of a matrix.
The determinant value of matrix in option (B) & (D) are positive but the determinant value of matrix in option (A) & (C) are negative.
Therefore, (B) & (D) can be represented as square of a matrix but (A) & (C) can’t.
Hence, the correct options are (A) and (C).
Q. If a chord, which is not a tangent, of the parabola y2 = 16x has the equation 2x + y = p, and midpoint (h, k), then which of the following is(are) possible value(s) of p, h and k ?
(A) p = 2, h = 3, k = –4
(B) p = 5, h = 4, k = –3
(C) p = –1, h = 1, k = –3
(D) p = –2, h = 2, k = –4
Q. The sides of a right angled triangle are in arithmetic progression. If the triangle has area 24, then what is the length of its smallest side?
