Select the set in which the numbers are related in the same way as are the numbers of the following sets. (NOTE : Operations should be performed on the whole numbers, without breaking down the numbers into their constituent digits. E.g. 13 – Operations on 13 such as adding / subtracting / multiplying etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.)
(19,21,55)
(8,9,23)
Check pattern:
(19, 21, 55)
→ 19 × 3 = 57, 57 − 2 = 55
and
(8, 9, 23)
→ 8 × 3 = 24, 24 − 1 = 23
So pattern:
(first × 3) − (second − first)
Now check option:
(22, 21, 67)
→ 22 × 3 = 66
→ 21 − 22 = −1
→ 66 − (−1) = 67 ✅
Correct Answer: (22, 21, 67)
