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

Team Careers360 25th Jan, 2024

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: $0$

Team Careers360 21st Jan, 2024

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 $0$.
