Question : Rs. 5000 is divided into two parts such that if one part is invested at 4% and the other at 5%, then the whole annual interest from both sums is 223. How much was invested at 4%?

Option 1: Rs. 2600

Option 2: Rs. 2700

Option 3: Rs. 2400

Option 4: Rs. 2300

Team Careers360 23rd Jan, 2024

Question : The two banks of a canal are straight and parallel. A, B, and C are three persons, of whom A stands on one bank and B and C on the opposite banks. B finds the angle ABC is 30°, while C finds that the angle ACB is 60°. If B and C are 100 metres apart, the breadth of the canal is:

Option 1: $\frac{25}{\sqrt{3}}$ metres

Option 2: $20\sqrt{3}$ metres

Option 3: $25\sqrt{3}$ metres

Option 4: $\frac{20}{\sqrt{3}}$ metres

Team Careers360 24th Jan, 2024

Correct Answer: $25\sqrt{3}$ metres


Solution :
BD = $x$ metre (let)
∴ CD = $(100 - x)$ metres
AD ⊥ BC; AD = $y$ metres
From ∆ ABD,
tan 30° = $\frac{AD}{BD}$
$⇒\frac{1}{\sqrt{3}}=\frac{y}{x}$
$\therefore x=\sqrt{3}y$ ----(1)
From ∆ACD,
$\tan 60° = \frac{AD}{CD}$
$⇒\sqrt{3}=\frac{y}{(100 - x)}$
$\therefore y=(100 - x)\sqrt{3}$
