Question : Directions: In the following question, select the related number from the given alternatives.
520 : 738 :: ? : 350
Option 1: 220
Option 2: 222
Option 3: 230
Option 4: 248
Correct Answer: 222
Solution : Given:
520 : 738 :: ? : 350
First, find the cube of the number and add the same number to the resultant number.
Like, 520 : 738→83 + 8 = 512 + 8 = 520; 93 + 9 = 729 + 9 = 738
Similarly, follow the same pattern for 350 : ?→73 + 7 = 343 + 7 = 350
Let's check the options –
First option: 220; 63 + 6 = 216 + 6 = 222 ≠ 220
Second option: 222; 63 + 6 = 216 + 6 = 222
Third option: 230; 63 + 6 = 216 + 6 = 222 ≠ 230
Fourth option: 248; 63 + 6 = 216 + 6 = 222 ≠ 248
So, only the second option follows the same pattern as followed by the given pair. Hence, the second option is correct.
