Question

Select the option in which the two numbers share the same relationship as that shared by the given number-pair.

4 : 68

1. 7 : 350
2. 3 : 27
3. 5 : 135
4. 6 : 225

Answer 1

Correct Answer - Option 1 : 7 : 350

The logic follows here is :

(First number)³ + (First number) = Second number.

4 : 68

4³ + 4 = 64 + 4 = 68.

Similarly,

(1). 7 : 350

7³ + 7 = 343 + 7 = 350.

(2). 3 : 27

3³ + 3 = 27 + 3 = 30 ≠ 27.

(3). 5 : 135

5³ + 5 = 125 + 5 = 130 ≠ 135.

(4). 6 : 225

6³ + 6 = 216 + 6 = 222 ≠ 225.

Hence, the correct answer is "7 : 350".
