What is the difference between Compound Interest and Simple Interest on Rs. 10,000 at \(5\%\) per annum for 2 years?
Correct Answer Logic:
SI \(= \dfrac{10000 \times 5 \times 2}{100} = 1000\). CI: Amount \(= 10000 \times (1.05)^2 = 10000 \times 1.1025 = 11025\). CI \(= 1025\). Difference \(= 1025 - 1000 = Rs.\ 25\).

Question 3365
If $\vec{a} \times (\vec{b} \times \vec{c}) = (\vec{a} \times \vec{b}) \times \vec{c}$, what can we conclude about vectors $\vec{a}$ and $\vec{c}$?
Correct Answer Logic:
Using vector triple product identity: $\vec{a} \times (\vec{b} \times \vec{c}) = (\vec{a} \cdot \vec{c})\vec{b} - (\vec{a} \cdot \vec{b})\vec{c}$ and $(\vec{a} \times \vec{b}) \times \vec{c} = (\vec{a} \cdot \vec{c})\vec{b} - (\vec{b} \cdot \vec{c})\vec{a}$. Equating gives $(\vec{a} \cdot \vec{b})\vec{c} = (\vec{b} \cdot \vec{c})\vec{a}$, implying $\vec{a}$ and $\vec{c}$ are parallel.

Correct Answer Logic:
MVT: $\frac{f(x) - f(0)}{x - 0} = f'(c) = e^c$. So $\frac{e^x - 1}{x} = e^c$, giving $e^x - 1 = xe^c$.
