Question Discussion & Solution

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)".

Letters are replaced by their place values as in the general alphabetical series.

Similarly,

Hence, answer is '14935'.

The given series is following-

For the first term 

15 + 20 = 35 

35 + 20 = 55

55 + 20 = 75

75 + 20 = 95

For the middle term

F + 2 = H

H + 2 = J

J + 2 = L

L + 2 = N

For the third term

35 + 35 = 70

70 + 35 = 105

105 + 35 = 140

140 + 35 = 175

Hence, the correct answer is 95 N 175.

Pages are necessary part of book. Book can be fiction or non-fiction. Pictures are not always necessary and not all books have learning. So, all other options are not necessary except Pages.
