The Logic here is as follows:

(1^st Number × 2^nd number) × 4 = 3^rd Number

In (6, 8, 192)

(1^st Number × 2^nd number) × 4

= (6 × 8) × 4

= 48 × 4

= 192 = 3^rd Number

Now check the all options,

Option (1) (12, 13, 263)

(1^st Number × 2^nd number) × 4

= (12 × 13) × 4

= 156 × 4

= 624 ≠ 3^rd Number

Option (2) (8, 11, 180)

(1^st Number × 2^nd number) × 4

= (8 × 11) × 4

= 88 × 4

= 352 ≠ 3^rd Number

Option (3) (11, 9, 396)

(1^st Number × 2^nd number) × 4

= (11× 9) × 4

= 99 × 4

= 396 = 3^rd Number

Option (4) (7, 5, 78)

(1^st Number × 2^nd number) × 4

= (7 × 5) × 4

= 35 × 4

= 140 ≠ 3^rd Number

Hence, the correct answer is "(11, 9, 396)".
