Answer / guna

9 times.
Initially, W-Num value will be 1.
1>9, so para will be executed. - 1 time
2>9, so para will be executed. - 2 times
3>9, so para will be executed. - 3 times
4>9, so para will be executed. - 4 times
5>9, so para will be executed. - 5 times
6>9, so para will be executed. - 6 times
7>9, so para will be executed. - 7 times
8>9, so para will be executed. - 8 times
9>9, so para will be executed. - 9 times
10>9, so para will not be executed

so para is executed for 9 times.
