Solve for A - C + E given A=4, B=6, C=9, D=2, E=12. The student's work shows 4 − 9 + 12 = 17, which is incorrect. 4-9

Here are the solutions to the quantitative questions:

Given values for substitution:
$A = 4$
$B = 6$
$C = 9$
$D = 2$
$E = 12$

Step 1: Solve Question 21
The question asks for the value of $A - C + E$.
Substitute the given values:

$$A - C + E = 4 - 9 + 12$$ $$4 - 9 + 12 = -5 + 12$$ $$= 7$$

The correct option is 'a'.
The student's work shows $4 - 9 + 12 = 17$, which is incorrect. $4 - 9
