Question : Two chords of a circle, $\overline{\mathrm{AB}}$ and $\overline{\mathrm{CD}}$, meet outside the circle at the point $\mathrm{P}$. If $\mathrm{m}(\overline{\mathrm{AP}})=200 \mathrm{~mm}, \mathrm{~m}(\overline{\mathrm{AB}})$ $=120 \mathrm{~mm}$, and $\mathrm{m}(\mathrm{CP}) = 160 \mathrm{~mm}$, what is the length of $\mathrm{CD}$?
Option 1: 100 mm
Option 2: 75 mm
Option 3: 60 mm
Option 4: 150 mm
Correct Answer: 60 mm
Solution : Let the chords $AB$ and $CD$ meet at $P$. We know that if two chords of a circle intersect externally, then the product of the lengths of the segments are equal. So, $AP\times BP = CP\times DP$ ⇒ $AP\times (AP – AB) = CP\times
Question : A fraction is greater than twice its reciprocal by $\frac{7}{15}$. What is the fraction?
Option 1: $\frac{3}{5}$
Option 2: $\frac{5}{3}$
Option 3: $\frac{3}{4}$
Option 4: $\frac{4}{3}$
Correct Answer: $\frac{5}{3}$
Solution : Let the fraction be $x$. According to the question, $x-\frac{2}{x}=\frac{7}{15}$ $\Rightarrow 15x^2-7x-30=0$ $\Rightarrow 15x^2-25x+18x-30=0$ $\Rightarrow 5x (3x-5)+6(3x-5)=0$ $\Rightarrow (3x-5)(5x+6)=0$ $\Rightarrow (3x-5)=0$ or $(5x+6)=0$ $\Rightarrow x=\frac{5}{3},\frac{-6}{5}$ Hence, the correct answer is $\frac{5}{3}$.

Question : Two circles touch each other externally. The radius of the first circle with centre O is 6 cm. The radius of the second circle with centre P is 3 cm. Find the length of their common tangent AB.
Option 1: $3\sqrt{2}$ cm
Option 2: $4\sqrt{2}$ cm
Option 3: $6\sqrt{3}$ cm
Option 4: $6\sqrt{2}$ cm
Correct Answer: $6\sqrt{2}$ cm
Solution : $R{_{C{_1}}} = 6$ cm $R{_{C{_2}}} = 3$ cm To find the length of the common tangent. Length of direct common tangent = $\sqrt{d^2 - (R{_{C{_1}}} - R{_{C{_2}}})^2}$ Where $d = R{_{C{_1}}} + R{_{C{_2}}} = 9$ cm $\therefore$ Length of common tangent $ = \sqrt{9^2

Question : S deposits a total of INR 50,000 in two accounts which give 8% and 12% simple Interest annually, respectively. After one year, he gets a total of INR 5,200. How much money does he deposit in the account with a 12% interest rate?
Option 1: INR 30,000
Option 2: INR 32,000
Option 3: INR 20,000
Option 4: INR 25,000
Correct Answer: INR 30,000
Solution : Let the amount in the account with 12% interest be $x$ and the amount in the account with 8% be (50000 – $x$). According to the question, $\frac{(50000-x)\times8}{100}+\frac{x\times 12}{100} = 5200$ ⇒ $400000-8x+12x = 520000$ ⇒ $4x=120000$ $\therefore x=30000$ Hence, the correct answer is
