Question

There are 4 expressions given below. 3 of them are similar and can be classified into a group. Which of these expressions form a group?
1) \(3! \times 4!\)
2) \(12 \times 12\)
3) \(198-44\)
4) \(\frac{576}{4}\)

• A. 1, 2 and 3
• B. 1, 3 and 4
• C. 2, 3 and 4
• D. 1,2 and 4

Answer 1

The Correct Option is D

Step 1: Observe the results of each operation:

• 31 × 4 = 124
• 12 × 12 = 144 
• 198 − 44 = 4.5
• 576 ÷ 4 = 144
• 1, 2, and 4 yield results in whole numbers.

Step 2: The odd one out is 3 because it yields a non-integer.

Conclusion: The correct group is 1, 2, and 4.
