Question 66

Simplify the expression $$25 - \left[16 - \left\{14 - \left(18 - \overline{8 + 3}\right) \right\}\right]$$.

Solution

$$25-\left[16-\left\{14-\left(18-\overline{8+3}\right)\right\}\right]=25-\left[16-\left\{14-\left(18-11\right)\right\}\right]$$

$$=25-\left[16-\left\{14-7\right\}\right]$$

$$=25-\left[16-7\right]$$

$$=25-9$$

$$=16$$

Hence, the correct answer is Option A
