    Question

    Study the given pattern carefully and select the number from among the options that can replace the question mark (?).

    A.

    16 ,15

    B.

    30 , 29

    C.

    18 , 10

    D.

    40 , 42

    Correct option is A

    Logic: 1st figure total side x 4 and 2nd figure total sides x 5 

    For 1st row:

    Total sides = 6. So, => 6 × 4 = 24

    Total sides = 3. So, => 3 × 5 = 15

    For 2nd row we have:

    Total sides = 5. So, => 5 × 4 = 20

      Total sides = 4. So, => 4 × 5 = 20

    Similarly, for the 3rd row, we have:

      Total sides = 4. => 4 × 4 = 16

     Total sides = 3. => 3 × 5 = 15

    Thus, the correct answer is:   16,  15.
