6	12	78
6	15	99
3	13	?

1. 49
2. 45
3. 54
4. 50

Answer 1

Correct Answer - Option 1 : 49

Here the pattern followed in each row is:

(1^st number + 1) × 2^nd number – 1st number = 3^rd number

Row 1: 6, 12, 78

= (6 + 1) × 12 - 6

= 7 × 12 – 6

= 84 – 6

= 78

Row 2: 6, 15, 99

= (6 + 1) × 15 - 6

= 7 × 15 – 6

= 105 – 6

= 99

Similarly

Row 3: 3, 13, ?

= (3 + 1) × 13 - 3

= 4 × 13 – 3

= 52 – 3

= 49

Hence, “49” is correct answer.
