Question : In a triangle ${ABC}, {AB}={AC}$ and the perimeter of $\triangle {ABC}$ is $8(2+\sqrt{2}) $ cm. If the length of ${BC}$ is $\sqrt{2}$ times the length of ${AB}$, then find the area of $\triangle {ABC}$.
Option 1: $32 \ cm^2$
Option 2: $28 \ cm^2$
Option 3: $16 \ cm^2$
Option 4: $36 \ cm^2$
Correct Answer: $32 \ cm^2$
Solution : Given: In a triangle ${ABC}, {AB}={AC}$ and the perimeter of $\triangle {ABC}$ is $8(2+\sqrt{2}) $ cm. The length of ${BC}$ is $\sqrt{2}$ times the length of ${AB}$. Let the sides $AB=AC=x$ cm. ⇒ $BC=\sqrt2x$ cm The perimeter of the triangle, $x+x+\sqrt2x=8(2+\sqrt2)$ ⇒ $x(2+\sqrt2)=8(2+\sqrt2)$

Question : In the given figure, PQR is a quadrant whose radius is 7 cm. A circle is inscribed in the quadrant as shown in the figure. What is the area (in cm2) of the circle?
Option 1: $385-221\sqrt{2}$
Option 2: $308-154\sqrt{2}$
Option 3: $154-77\sqrt{2}$
Option 4: $462-308\sqrt{2}$
Correct Answer: $462-308\sqrt{2}$
Solution :
Let the radius of the circle = $r$ cm The radius of the quadrant = QM = QR = QP = 7 cm From the figure, $OS=OT=OM=QT=r$ cm ⇒ $OQ=(7-r)$ cm In $\triangle QTO$, $OQ^2=OT^2+QT^2$ ⇒ $(7-r)^2=r^2+r^2$ ⇒ $(7-r)^2=2r^2$ ⇒ $7-r=r\sqrt2$ ⇒ $r=\frac{7}{\sqrt2+1}=7(\sqrt2-1)$ The area
Question : The following pie charts show the number of start-ups started in various sectors since 2016 and the number of successful start-ups in those sectors respectively. Out of all the start-ups that started in 2016, what percentage (approx. up to two decimal places) started in the travel sector?
Option 1: $13.12 \%$
Option 2: $12.19 \%$
Option 3: $12.91 \%$
Option 4: $13.21 \%$
Correct Answer: $12.91 \%$
Solution : Total number of startups = 560 + 720 + 324 + 650 + 256 = 2510 Number of startups in the travel sector = 324 Percentage of startups in travel sector = $\frac{324}{2510}\times 100=12.91\%$ Hence, the correct answer is $12.91\%$
Question : Directions: If 5 * 3 = 19 and 8 * 5 = 49, then what should be the value of 6 * 4 = ?

Option 4: 16
Correct Answer: 28
Solution : Given: 5 * 3 = 19 8 * 5 = 49
(5 * 3) = 19→(5)2 – {(5 – 3) × 3} = 25 – {2 × 3} = 25 – 6 = 19 (8 * 5) = 49→(8)2 – {(8 – 5)
