Correct Answer: 25


Solution : Given:
First row – 7, 343, 49
Second row– 6, 216, 36
Third row– 5, 125, ?

In each row, the second number is the cube of the first number, and the third number is the square of the first number.
Like, first row: 7, 343, 49→(7) 3 = 343; (7) 2 = 49
And, second row: 6, 216, 36→(6) 3 = 216; (6) 2 = 36
Similarly, follow the same pattern for the third row 5, 125, ?→(5) 3 = 125; (5) 2 = 25

So, the missing number is 25. Hence, the third option is correct.
