What is the result of the expression 5 * (1 + 2) - 3 in C?

What is the result of the expression 5 * (1 + 2) - 3 in C? Correct Answer 12

In C, arithmetic expressions follow the order of operations (PEMDAS/BODMAS), where parentheses have the highest precedence. Therefore, the expression (1 + 2) inside the parentheses is evaluated first, resulting in 3. Then, the multiplication is performed: 5 * 3, which equals 15. Finally, the subtraction is performed: 15 - 3, which equals 12.

Option B (15) is incorrect because it represents the result of the multiplication but doesn't consider the subsequent subtraction.
Option C (10) is incorrect because it doesn't represent the correct result of the expression.
Option D (6) is incorrect because it doesn't consider both the multiplication and subtraction; the correct result is 12.

Consider evaluating the following expression tree on a machine with load-store Architecture in which memory can be accessed only through load and store instructions. The variables a, b, c, d and e are initially stored in memory. The binary operators used in this expression tree can be evaluated by the machine only when the operands are in registers. The instructions produce result only in a register. If no intermediate results can be stored in memory, what is the minimum number of registers needed to evaluate this expression?

Amitabh picks a random integer between 1 and 999, doubles it and gives the result to Sashi. Each time Sashi gets a number from Amitabh, he adds 50 to the number, and gives the result back to Amitabh, who doubles the number again. The first person, whose result is more than 1000, loses the game. Let 'X' be the smallest initial number that results in a win for Amitabh. The sum of the digit of 'X' is:
