Question : If $x+\frac{16}{x}=8$, then the value of $x^2+\frac{32}{x^2}$ is:
Option 1: 20
Option 2: 24
Option 3: 16
Option 4: 18
Correct Answer: 18
Solution : Given: The value of $x+\frac{16}{x}=8$. We know the algebraic identity, $(a–b)^2=a^2+b^2–2ab$. $x+\frac{16}{x}=8$ ⇒ $x^2+16=8x$ ⇒ $x^2–8x+16=0$ ⇒ $(x–4)^2=0$ ⇒ $x=4,4$ The value of $x^2+\frac{32}{x^2}$ is given as, ⇒ $4^2+\frac{32}{4^2}=16+\frac{32}{16}$ = $16+2=18$ Hence, the correct answer is 18.
Question : The income of A is $\frac{2}{3}$ of B's income and the expenditure of A is $\frac{3}{4}$ of B's expenditure. If $\frac{1}{3}$ of the income of B is equal to the expenditure of A, then the ratio of the savings of A to those of B is:
Option 1: 5 : 3
Option 2: 3 : 5

Option 1: 14.5 cm
Option 2: 22.5 cm
Option 3: 12 cm
Option 4: 8 cm
Correct Answer: 14.5 cm
Solution : Given: CD = 8 cm, PD = 10 cm, and PB = 8 cm $\therefore$ PC = CD + PD = 8 + 10 = 18 cm If two chords, AB and CD, of a circle intersect at a point P outside the circle,
