Question : What is the value of $(1 ÷ 4) + (1 ÷ 6) - \left \{(1 ÷ 8) ÷ (1 ÷ 4) \right \}$?
Option 1: $-(11÷12)$
Option 2: $-(5÷12)$
Option 3: $-(7÷12)$
Option 4: $-(1÷12)$
Correct Answer: $-(1÷12)$
Solution : $(1 ÷ 4) + (1 ÷ 6) - \left \{(1 ÷ 8) ÷ (1 ÷ 4) \right \}$ $=(\frac{1}{4}) + (\frac{1}{6}) - {\frac{(\frac{1}{8})}{(\frac{1}{4})}}$ $=\frac{1}{4} + \frac{1}{6} - \frac{1}{2}$ $=\frac{3+2-6}{12}$ $=-\frac{1}{12}$ $= -(1÷12)$ Hence, the correct answer is $-(1÷12)$.
Question : If $6x^{2}-12x+1=0$, then the value of $27x^{3}+\frac{1}{8x^{3}}$ is:
Option 1: 162
Option 2: 189
Option 3: 207
Option 4: 225
Correct Answer: 189
Solution : Given: $6x^{^2}-12x+1=0$ Dividing by $2x$, we get $3x+\frac{1}{2x}=6$ Cubing both sides, $\left (3x \right)^{3}+\left (\frac{1}{2x} \right )^{3}+3\left (3x \right)\left (\frac{1}{2x}\right )\left (3x+\frac{1}{2x} \right )=6^{3}$ ⇒ $27x^{3}+\frac{1}{8x^{3}}+3\left (3\right )\left (\frac{1}{2} \right )\left (6\right )=6^{3}$ ⇒ $27x^{3}+\frac{1}{8x^{3}}=6^{3}-3\left (3\right)\left (\frac{1}{2}\right)\left (6\right)=189$ Hence, the correct answer is 189.
