Four numbers are given out of which three are alike in some manner while one is different. Choose the combination which follows the same pattern.
A. 196
B. 484
C. 175
D. 225
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → A, B and D only
A. 196 — \(14\times14=14^{2}\), a perfect square.
B. 484 — \(22\times22=22^{2}\), a perfect square.
C. 175 — it lies between \(13^{2}=169\) and \(14^{2}=196\), so it is not a perfect square, and 175 is the odd one out.
D. 225 — \(15\times15=15^{2}\), a perfect square.
196, 484 and 225 are alike because all three are perfect squares.
