Answer 2

Answer:- (D) 74

Step wise solution:

$({7}^{2} - 4^{2}) - 3^{2} \\ = ( 49 - 16) - 9 \\= 33 - 9 = 24$

Hence, Interchanging 24 we get 42

Similarly,

$( {8}^{2} - {6}^{2} ) - {3}^{2} \\ = (64 - 36) - 9 \\ = 28 - 9 = 19$

Hence, Interchanging 19 we get 91

Similarly,

$( {9}^{2} - {5}^{2} ) - {3}^{2} \\ (81 - 25) - 9 \\ = 56 - 9 = 47$

Hence, Interchanging 47 we get 74 .
