                       ANSWER : HERE IS THE ANSWER FOR YOUR QUESTION:

  

                       ------------------------------------------------------------------------------------------------------

here we are given 2 processes as A and B which do not execute the critical section area .

so these will be not be synchronized , so will be executed in the one by one manner . first

process A will be executed and then process B will be executed .

initially , the value of I is 0 .

now , the process A increments value OF I 10 times .. so the final value of I after Process A finishes will   be 10

after this , process B start to execute and then it decrement the value by 25 . so the value will become as 10-25=-14

so , the final value of the I would be -14 as 0 value would also be reached

thus , the final value is -14
