\(\begin{array}{*{20}{c}} {25}&{40}&{10}\\ {81}&9&9\\ ?&{16}&8 \end{array}\)

1. 30
2. 34
3. 36
4. 32

Answer 1

Correct Answer - Option 4 : 32

The logic follows here is:

The sum of multiplication of first and second number = (third number)³

In Row 1:

25 × 40 = 10³

1000 = 10³

1000 = 1000

In Row 2:

81 × 9 = 9³

729 = 9³

729 = 729

Similarly, 

In Row 3:

? × 16 = 8³

? × 16 = 512

? = 512 / 16

? = 32

Hence, the correct answer is "32".
