    Using matrix calculation and determinant form , answer of this question is 97.
    See the similarities-
    (7*-13)+(5*30)+42=101
    (6*-13)+(2*30)+42=24
    (8*-13)+(3*30)+42=28
    hence ,
    (5*-13)+(4*30)+42=97
    Why we multiply greater term by -13 and lesser term by 30 and add 42, if you are interested to know that you can use inverse matrix method for this.
