Question : A dishonest trader says to customers that he sells his goods at a cost price, but he uses a false weight and gains 12.5% as profit. How many grams does he use to weight 1 kg?
Option 1: 900 g
Option 2: 880.5 g
Option 3: 850 g
Option 4: 888.8 g
Correct Answer: 888.8 g
Solution : According to the formula, $12.5\% = [\frac{\text{Error}}{\text{1000 – Error}}] × 100$ ⇒ $\frac{1}{8} = [\frac{\text{Error}}{\text{1000 – Error}}]$ ⇒ $8\text{Error} = \text{(1000 – Error)}$ ⇒ $\text{8Error + Error} = 1000$ ⇒ $9\text{Error} = 1000$ ⇒ $\text{Error} = \frac{1000}{9}$ So, the trader gives $1000 - \frac{1000}{9}=\frac{8000}{9}=888.8$
Question : If $x = \sqrt[3]{5} + 2$, then the value of $x^3-6x^2+12x-13$ is:
Option 1: $–1$
Option 2: $1$
Option 3: $2$
Option 4: $0$
Correct Answer: $0$
Solution : $x = \sqrt[3]{3} + 2$ ⇒ $x - 2 = \sqrt[3]{5}$ By cubing on both the sides, $⇒x^3-6x^2+3x (-2)^2-2^3=5$ [since $(a - b)^3 = a^3 - 3a^2b + 3ab^2 - b^3$] $⇒x^3-6x^2+12x-8-5=0$ $⇒x^3-6x^2+12x-8-5=0$ $⇒x^3-6x^3+12x-13=0$ Hence, the correct answer is $0$.
