Question : ' O ' is a point in the interior of an equilateral triangle. The perpendicular distance from ' O ' to the sides are $\sqrt{3}~cm, 2 \sqrt{3}~cm, 5 \sqrt{3}~cm$. The perimeter of the triangle is:
Option 1: 48 cm
Option 2: 32 cm
Option 3: 24 cm
Option 4: 64 cm
Correct Answer: 48 cm
Solution : Perpendicular distance = $p{_1} = \sqrt{3}$ $p{_2} =2\sqrt{3}$ $p{_3} = 5\sqrt{3}$ Height of an equilateral triangle = $\frac{\sqrt{3} \times (a)}{2}$ Height of an equilateral triangle = sum of perpendicular distance with point The perimeter of an equilateral triangle = $3\times a$ Height of equilateral
Question : If $a + b = 11$ and $ab=35$, then what is the value of $\left(a^4+b^4\right)$?
Option 1: 151
Option 2: 261
Option 3: 124
Option 4: 102
Correct Answer: 151
Solution : Given, $a + b = 11$ and $ab=35$ Consider, $a+b=11$ Squaring both sides, we get, ⇒ $(a+b)^2=11^2$ ⇒ $a^2+b^2+2ab=121$ ⇒ $a^2+b^2+2(35)=121$ ⇒ $a^2+b^2+70=121$ ⇒ $a^2+b^2=51$ Squaring both sides, ⇒ $(a^2+b^2)^2=51^2$ ⇒ $a^4+b^4+2a^2b^2=2601$ ⇒ $a^4+b^4+2(35)^2=2601$ ⇒ $a^4+b^4+2\times1225=2601$ ⇒ $a^4+b^4+2450=2601$ ⇒ $a^4+b^4=2601-2450$ $\therefore a^4+b^4=151$ Hence, the correct

Question : A metallic solid spherical ball of radius 3 cm is melted and recast into three spherical balls. The radii of two of these balls are 2 cm and 1.5 cm. What is the surface area (in cm2) of the third ball?
Option 1: $50 \pi$
Option 2: $\frac{25}{4} \pi$
