How to write a formula with multiple IF(If)?

Question

Spreadsheets

Good afternoon.
Please help me write the formula.
There is a Cell in which there can be two fixed values ​​YES/NO.
I wrote a formula for the value YES:

=IF(IF(C2="YES"; E2>=250);"Passed";"Not done")

Formula for NO value:

=IF(IF(C2="NO"; E2>=150);"Passed";"Not completed")

How to combine them into one formula?

Answer 1

=IF(C2="ДА";IF(E2>=250;"Выполнен";"Не выполнен");IF(E2>=150;"Выполнен";"Не выполнен"))

Answer 2

Fuck the old formula. New.

=IF(OR(AND(C2="Yes";E2>=250);AND(C2="No";E2>=150));"OK";"Bad")
