Question 58

What is the value of A if $$A = \left[50 - 4 \times 5 + {6 \div 3 - 1}\right]$$?

Solution

$$\left[50-4\times\ 5+\frac{6}{3}-1\right]?$$

$$\left[50-4\times\ 5\ +\ 2-1\right]?$$

$$\left[50-20+2-1\right]$$

$$\left[30+2-1\right]?$$

$$\left[32-1\right]?$$

$$\left[31\right]$$

Hence option C is the correct answer
