Question:


If 72 ▆ 96 = 6927, 58 ▆ 87 = 7885, then 79 ▆ 86 = ? 


    (A) 7689 


    (B) 8976 


    (C) 6897 


    (D) 6978



Solution:


Let's analyse the pattern:

  1. 72 ▆ 96 = 6927:

    • The digits of 96 are reversed to get 69, and the digits of 72 are reversed to get 27.

    • The combined result is 6927.

  2. 58 ▆ 87 = 7885:

    • The digits of 87 are reversed to get 78, and the digits of 58 are reversed to get 85.

    • The combined result is 7885.

Following this pattern:

  1. 79 ▆ 86 = ?:

    • Reverse the digits of 86 to get 68, and reverse the digits of 79 to get 97.

    • The combined result is 6897.

The correct answer is (C) 6897.
