Correct Answer: 252
Solution :
Given:
21 : 196 :: 29 : ? :: 38 : 315
Here, multiply the first number by 7 and then add the square of 7 to the resultant.
21 : 196→(21 × 7) + (7)
2
= 147 + 49 = 196
38 : 315→(38 × 7) + (7)
2
= 266 + 49 = 315
Similarly, follow the same pattern for 29 : ?→(29 × 7) + (7)
2
= 203 + 49 = 252
So, 252 is related to 29 in the same way as the second term is related to the first term, and the sixth term is related to the fifth term. Hence, the second option is correct.
