Question

6636 | 3
8118 | 4
2212 | 0
8688 | ?
5971 | ?

Explanation:

Step1: Analyze the pattern for the first three numbers

For \(6636\): Count the number of closed loops (holes) in each digit. \(6\) has 1 loop, another \(6\) has 1 loop, \(3\) has 0, \(6\) has 1. Total loops: \(1 + 1+ 0 + 1=3\) (matches the right number).
For \(8118\): \(8\) has 2 loops, \(1\) has 0, \(1\) has 0, \(8\) has 2. Total loops: \(2 + 0+ 0 + 2 = 4\) (matches the right number).
For \(2212\): \(2\) has 0, \(2\) has 0, \(1\) has 0, \(2\) has 0. Total loops: \(0+0 + 0+0 = 0\) (matches the right number).

Step2: Apply the pattern to \(8688\)

Digits: \(8\) (2 loops), \(6\) (1 loop), \(8\) (2 loops), \(8\) (2 loops). Total loops: \(2 + 1+ 2 + 2=\boldsymbol{7}\).

Step3: Apply the pattern to \(5971\)

Digits: \(5\) (0 loops), \(9\) (1 loop), \(7\) (0 loops), \(1\) (0 loops). Total loops: \(0 + 1+ 0 + 0=\boldsymbol{1}\).

Answer:

For \(8688\), the answer is \(7\); for \(5971\), the answer is \(1\).
