The solution says the answer is C
Ans 2:
Class : Class 9
Assuming that the language used is java.
So there is something called precedence of operators. unary + and unary - have a precedence of 13 while Modulus (Mod) has a precedence of 12 which is lower than that of + and -. this is how the calculation takes place :
res = 9 Mod 2 + 1 - 2;
res = 9 Mod 3 - 2;
res = 9 Mod 1;
res = 0; (Remainder of 9 / 1 = 0)
Hope you understand. Best of luck for your Exams! : )
