    @Ankit fork is a system call which generates new thread of execution,and returns pid of newly created thread to parent process and a value of 0 to child process.so here in second statement when fork is called 0 will be returned for child processes so they will not execute second fork in this call.so,doing in the same way you will get 20 as total no of processes created.
