6	14	?
42	68	92

1. 23

Answer 1

Correct Answer - Option 1 : 23

Given,

10	17	8
5	3	15
6	14	?
42	68	92

 

The pattern followed here is,

Column 1:

10 * 2 = 20, 5 * 2 = 10, 6 * 2 = 12

So, 20 + 10 + 12 = 42

Column 2:

17 * 2 = 34, 3 * 2 = 6, 14 * 2 = 28

So, 34 + 6 + 28 = 68

Column 3:

8 * 2 = 16, 15 * 2 = 30, X * 2 = 2X

16 + 30 + 2X = 92

2X + 46 = 92

2X = 92 - 46 = 46

So, X = 23

Hence, the answer is 23.
