Question : What is the simplified value of $\left(1-\frac{1}{4-\frac{2}{1+\frac{1}{\frac{1}{3}+2}}}\right) \times \frac{15}{16} \div \frac{2}{3}$ of $2 \frac{1}{4}-\frac{3+4}{3^3+4^3}$
Option 1: $\frac{5}{13}$
Option 2: $\frac{4}{13}$
Option 3: $\frac{8}{13}$
Option 4: $\frac{6}{13}$
Correct Answer: $\frac{4}{13}$
Solution : Given: $\left(1-\frac{1}{4-\frac{2}{1+\frac{1}{\frac{1}{3}+2}}}\right) \times \frac{15}{16} \div \frac{2}{3}$ of $2 \frac{1}{4}-\frac{3+4}{3^3+4^3}$ $=(1-\frac{1}{4-\frac{2}{1+\frac{3}{7}}}) \times \frac{15}{16} \div (\frac{2}{3} \times \frac{9}{4})-\frac{3+4}{27+64}$ $=(1-\frac{1}{4-\frac{14}{10}}) \times \frac{15}{16} \div \frac{3}{2} -\frac{7}{91}$ $=(1-\frac{10}{26}) \times \frac{15}{16} \times \frac{2}{3} -\frac{1}{13}$ $=\frac{16}{26} \times \frac{5}{8} -\frac{1}{13}$ $=\frac{10}{26} -\frac{1}{13}$ $=\frac{10-2}{26}$ $=\frac{8}{26}$ $=\frac{4}{13}$ Hence, the correct answer is $\frac{4}{13}$.
Question : $P Q R S$ is a rectangle. $T$ is a point on $P Q$ such that $R T Q$ is an isosceles triangle and $P T=5 \mathrm{QT}$. If the area of triangle RTQ is $12 \sqrt{3}$ sq.cm, then the area of the rectangle PQRS is:
Option 1: $144 \sqrt{3}$ sq.cm
Option 2: $142$ sq. cm
Option 3: $134 \sqrt{3}$ sq. cm
Option 4: $142\sqrt{3}$ sq. cm
Correct Answer: $144 \sqrt{3}$ sq.cm
Solution : Given: $PT = 5QT$ $PT : QT = 5 : 1$ Let the ratio of $PT : QT$ be $5x : x$. ⇒ $PQ = PT + QT$ ⇒ $PQ = 5x + x$ ⇒ $PQ = 6x$ Area of $\triangle RTQ =
Question : DEF is an isosceles triangle such that DE = DF = 60 cm and EF = 96 cm. DG is a median to base EF. What is the length of DG?
Option 1: 22 cm
Option 2: 36 cm
Option 3: 24 cm
Option 4: 32 cm
Correct Answer: 36 cm
Solution : Given: DE = DF = 60 cm, EF = 96 DG median cuts EF into two halves. So, EG = $\frac{96}{2}=48$ cm In $\triangle$DEG, DE2 = DG2 + EG2 ⇒ DG = $\sqrt{60^2-48^2}=\sqrt{1296}=36$ cm Hence, the correct answer is 36 cm.
