Correct Answer: 32


Solution : The cube root of the product of the first and second numbers is equal to the third number –
Row I: 25 × 40 = $\sqrt[3]{1000 }$ = 10
Row II: 81 × 9 = $\sqrt[3]{729}$ = 9
Similarly, in Row III: X × 16 = 8 3
⇒ X = 512 ÷ 16
⇒ X = 32

So, the missing number is 32. Hence, the fourth option is correct.
