Correct Answer: 23


Solution : Given:

134 34 100
117 86 31
87 ? 64

In each row, the third number is the difference between the first two.
Row 1: 134 – 34 = 100
Row 2: 117 – 86 = 31
Row 3: 87 – (?) = 64
⇒ (?) = 87 – 64
⇒ (?) = 23

So, 23 is the missing number. Hence, the second option is correct.
