Hey student,

As you have mentioned your income was 60000 but now it is 100000 they'll not reject it if the change in income is after the filling of application as income might be up or down and also if the average income of yours is 60000. Example your last month income was 50000 and this month is 70000 the average will be near 60000 in this case also they'll not reject the application.

All the best student,

Hope this helps you.
