Select the option in which the numbers are related in the same way as are the numbers in the given set.

(343, 98, 21)

(1331, 242, 33)

(343, 98, 21)

The logic followed here is :

Number³ , (Number + Number)× Number , Number × 3

(343, 98, 21)

7³ = 343

and  98 = (7 + 7) × 7

98 = 14 × 7

And

21 = 7 × 3

Similarly

(1331, 242, 33)

11³ = 1331

and  242 = (11 + 11) × 11

242 = 22 × 11

And

33 = 11 × 3
