Option 4: 372
Correct Answer: 362
Solution :
Given:
196 : 226 :: 256 : 290 :: 324 : ?
Like, 196 : 226→(14)
2
= 196; 226 – 1 = 225 = (15)
2
(14 and 15 are consecutive numbers.)
256 : 290→(16)
2
= 256; 290 – 1 = 289 = (17)
2
(16 and 17 are consecutive numbers.)
Similarly, for 324 : ?→(18)
2
= 324; (?) – 1 = (19)
2
⇒ (?) – 1 = (19)
2
⇒ (?) – 1 = 361
⇒ (?) = 361 + 1
⇒ (?) = 362
So, 362 is related to 324. Hence, the first option is correct.
