Question

If 17 $ 22 = 4 and 56 $ 13 = 7, then find the value of 71 $ 25 = ?
1. 1
2. 56
3. 8
4. 96

Answer 1

Correct Answer - Option 1 : 1

The logic is:

17 $ 22 = (1 + 7) - (2 + 2) = 8 - 4 = 4

56 $ 13 = (5 + 6) - (1 + 3) = 11 - 4 = 7

Similarly,

71 $ 25 = (7 + 1) - (2 + 5) = 8 - 7 = 1

Hence, '1' is the correct answer.
