Question : In the figure, chords XY = $x$ cm and PQ = 10 cm intersect each other at point L. Find the length of XY (in cm).
Option 1: 22
Option 2: 21
Option 3: 20
Option 4: 23
Correct Answer: 20
Solution : For two chords, PQ and XY intersect each other externally at L, QL × PL = YL × XL ⇒ $6 × (10+6) = 4 × (x+4)$ ⇒ $x+4=24$ $\therefore x=20$ Hence, the correct answer is 20 cm.

Question : Rajeev invested Rs. 3,000 for 2 years at compound interest (compounded annually) in a company that paid him interest of Rs.1,320. What will be the annual rate of interest at which Rajeev invested his money?
Option 1: 30 percent
Option 2: 24 percent
Option 3: 16 percent
Option 4: 20 percent
Correct Answer: 20 percent
Solution : Given, Principal ($P$) = Rs. 3000 Compound Interest ($CI$) = Rs. 1320 Time (t) = 2 years We know, $CI = P(1 + \frac{r}{100})^t - P$ ⇒ $1320 = 3000(1+\frac{r}{100})^2 - 3000$ ⇒ $1320+3000 = 3000(1+\frac{r}{100})^2$ ⇒ $\frac{4320}{3000}=(1+\frac{r}{100})^2$ ⇒ $\sqrt{1.44}=(1+\frac{r}{100})$ ⇒ $1.2 = (1+\frac{r}{100})$
