Select the set in which the numbers are related in the same way as are the numbers ofthe following sets.

(NOTE : Operations should be performed on the whole numbers, without breaking down the numbers into its constituent digits. E.g. 13 – Operations on 13 such as adding /subtracting /multiplying etc. to 13 can be performed. Breaking down 13 into 1and 3 and then performing mathematical operations on 1 and 3 is not allowed)

(24, 12, 169)

(66, 14, 263)​​

Given: 

(24, 12, 169)

(66, 14, 263)

Logic: Square of 2nd number + (1st number + 1) = 3rd number 

For, (24, 12, 169)

12² = 144

144 + (24 + 1) = 169

For, (66, 14, 263)

14² = 196

196 + (66 + 1) = 263

Now, we check each options.

Option (a): (25, 11, 127)  (Not Follow)

11² = 121

25 + (121 + 1) = 147 $$\neq$$​ 127

Option (b): (47, 15, 273) (Follow)​

15²= 225

225 +(47 + 1) = 273

Option (c): (61, 13, 211) (Not Follow)​

13² = 169

169 + (61 +1) = 231 $$\neq$$ 211

Option (d): (21, 17, 210) (Not Follow)​

17² = 289

289 + (21 + 1) = 311 $$\neq$$​ 210

Thus, correct option is (b).
