    Question

    What is the missing number in the given diagram?

    A.

    6

    B.

    4

    C.

    8

    D.

    5

    Correct option is B

    Logic: The sum of numbers inside three circles in each diagonal should be 15.
    Checking the first diagonal (top-right to bottom-left):
    Numbers in this diagonal: 7, 3, 5
    Sum: 7 + 3 + 5 = 15 
    Checking the Middle diagonal (top-right to bottom-left):
    Numbers in this diagonal: 5, 4, 6
    Sum: 5 + 4 + 6 = 15 
    Finding the missing number in the last diagonal (3, 8, ? = 15):
    Given numbers: 3, 8, ?
    Sum: 3 + 8 + ? = 15
    ? = 15 - (3 + 8) = 15 - 11 =
    Thus, the correct option is (b) 4
