    Answer:

    The correct answer is – 25.

    Explanation:

    Given:

    Sum of the 3 consecutive odd numbers = 69

    solution:

    Let’s assume the initial number – 2X+1

    Let’s say the second number is -‘2X+3’ and

    Let’s say the largest number is- ‘2X+5’.

    Sum of the numbers = 69

    (2X+1) + (2X+3) + (2X+5) = 69

    6X+9 = 69

    6X = 69–9

    6X = 60

    X = 60/6

    X= 10

    So, x value would be 10. Putting value of X in 2X+5

    = 2(10)+5

    =25

    = 25 (Answer)
