Question : $\triangle PQR$ is a right-angled triangle. $\angle Q = 90^\circ$, PQ = 12 cm, and QR = 5 cm. What is the value of $\operatorname{cosec}P+\sec R$?
Option 1: $\frac{26}{5}$
Option 2: $\frac{13}{5}$
Option 3: $\frac{18}{5}$
Option 4: $\frac{14}{5}$
Correct Answer: $\frac{26}{5}$
Solution : As $PR^2=PQ^2+QR^2$ ⇒ $PR^2=12^2+5^2$ ⇒ $PR^2=144+25$ ⇒ $PR^2=169$ ⇒ $PR=\sqrt{169}$ ⇒ $PR=13$ cm Now, $\operatorname{cosec} \ P=\frac{PR}{QR}=\frac{13}{5}$ and $\sec R=\frac{PR}{QR}=\frac{13}{5}$ $\therefore \operatorname{cosec} \ P+\sec R=\frac{13}{5}+\frac{13}{5}=\frac{26}{5}$ Hence, the correct answer is $\frac{26}{5}$.
Question : Directions: What should come in place of X in the given series? 23, 31, 47, 71, 103, X

Question : Which of the following equations has 7 as a root?
Option 1: $3x^2-6x+2=0$
Option 2: $x^2-9x+14=0$
Option 3: $x^2-7x+10=0$
Option 4: $x^2+3x-12=0$
Correct Answer: $x^2-9x+14=0$
Solution : Given: Option 1: $3x^2-6x+2=0$ Using the quadratic formula, we get, $⇒x=\frac{6\pm\sqrt{(-6)^2-4.3.2}}{2.3}$ So, $x=\frac{\sqrt3+3}{3}$ or $x=\frac{-\sqrt{3}+3}{3}$ So, the value of $x\neq7$. Option 2: $x^2-9x+14=0$ $⇒x^2-7x-2x+14=0$ $⇒(x-7)(x-2)=0$ $\therefore x = 7$ or $x = 2$ Here, the value of $x=7$. Hence, the correct answer is $x^2-9x+14=0$.
