    After interchanging the first and last digits in each of the following numbers, identify the correct sequence of number in the ascending order.

    (A) 146

    (B) 453

    (C) 678

    (E) 942

    Choose the correct answer from the options given below:

    A (A), (Ε), (B), (C), (D) Correct Answer Incorrect Answer
    B (C), (B), (D), (A), (C) Correct Answer Incorrect Answer
    C (A), (B), (D), (E), (C) Correct Answer Incorrect Answer
    D (E), (B), (D), (A), (C) Correct Answer Incorrect Answer

    Solution

    (A) 146 -> After interchange: 641 (B) 453 -> After interchange: 354 (C) 678 -> After interchange: 876 (D) 254 -> After interchange: 452 (E) 942 -> After interchange: 249 Now, let's arrange these numbers in ascending order:

    1. 249 (from E)
    2. 354 (from B)
    3. 452 (from D)
    4. 641 (from A)
    5. 876 (from C)
    So, the correct sequence of numbers in ascending order after interchanging the first and last digits is: E, B, D, A, C, which corresponds to 249, 354, 452, 641, 876.
