Correct Answer: 19 : 361 : 342


Solution : Given:
11 : 121 : 110 :: 15 : 225 : 210 :: ?

Like, 11 : 121 : 110→11 2 = 121; 121 – 11 = 110
15 : 225 : 210→15 2 = 225; 225 – 15 = 210
Let's check the options –
First option: 9 : 81 : 70; 9 2 = 81; 81 – 9 = 72 ≠ 70
Second option: 19 : 361 : 342; 19 2 = 361; 361 – 19 = 342
Third option: 17 : 288 : 272; 17 2 = 289 ≠ 288; 289 – 17 = 272
Fourth option: 16 : 255 : 239; 16 2 = 256 ≠ 255; 256 – 16 = 240 ≠ 239

Hence, the second option is correct.
