Class XII A determinant is unaltered , if Two rows are interchanged Two columns are interchanged Every element in a column is multiplied by the same factor To each element of any row is added the corresponding element of the other row multiplied by a given factor The point (3, 2 ) is reflected in the y – axis and then moved a distance of 5 units towards the negative side of y – axis .The co – ordinates of the point thus obtained are (3,–3) (–3,3) (–3,–3) (3,3) The system of equationsx+2y =5 , 4x+8y =20 has no solution a unique solution infinitely many solutions none of these. If the entries in a 3 x 3 determinant are either 0 or 1 , then the greatest value of this determinant is : 1 0 None of these 2 In a third order determinant , each element of the first column consists of sum of two terms , each element of the second column consists of sum of three terms and each element of the third column consists of sum of four terms . Then it can be decomposed into n determinants , where n has value 1 24 9 16 Do you really want to submit this quiz? Cancel Submit Quiz
