Question : The side of an equilateral triangle is 36 cm. What is the radius of the circle circumscribing this equilateral triangle?
Option 1: $13 \sqrt{3} \mathrm{~cm}$
Option 2: $10 \sqrt{3} \mathrm{~cm}$
Option 3: $12 \sqrt{3} \mathrm{~cm}$
Option 4: $9 \sqrt{3} \mathrm{~cm}$
Correct Answer: $12 \sqrt{3} \mathrm{~cm}$
Solution : Length of side of given equilateral triangle, $a$ = 36 cm We know that circumradius of an equilateral triangle $=\frac{a}{\sqrt{3}}=\frac{36}{\sqrt{3}}=12\sqrt{3}$ Hence, the correct answer is $12 \sqrt{3} \mathrm{~cm}$.
Question : Cement is made hard with
Option 1: Dehydration
Option 2: Hydration and dissociation of water

Cement hardens due to hydration, chemical reactions that occur independently of the water concentration of the mixture, they will harden even while submerged or regularly exposed to damp conditions. When anhydrous cement powder
Question : If $\frac{\sqrt{38-5 \sqrt{3}}}{\sqrt{26+7 \sqrt{3}}}=\frac{a+b \sqrt{3}}{23}, b>0$, then the value of $(b-a)$ is:
Option 1: 7
Option 2: 18
Option 3: 29
Option 4: 11
Correct Answer: 29
Solution : $\frac{\sqrt{38-5 \sqrt{3}}}{\sqrt{26+7 \sqrt{3}}}=\frac{a+b \sqrt{3}}{23}, b>0$ $⇒\frac{\sqrt{38-5 \sqrt{3}}}{\sqrt{26+7 \sqrt{3}}}=\frac{a+b \sqrt{3}}{23}$ $⇒\frac{\sqrt{(38-5 \sqrt{3)}({26-7 \sqrt{3}})}}{\sqrt{(26+7 \sqrt{3})({26-7 \sqrt{3}})}}=\frac{a+b \sqrt{3}}{23}$ $⇒\frac{\sqrt{(988+105-396\sqrt3)}}{\sqrt{(529)}}=\frac{a+b \sqrt{3}}{23}$ $⇒\frac{\sqrt{(11^2+(18\sqrt3)^2-2\times11\times18\sqrt3)}}{\sqrt{(23^2)}}=\frac{a+b \sqrt{3}}{23}$ $⇒\frac{\sqrt{(18\sqrt3-11)^2}}{23}=\frac{a+b \sqrt{3}}{23}$ $⇒\frac{(18\sqrt3-11)}{23}=\frac{a+b \sqrt{3}}{23}$ On comparing, $a=-11$ and $b=18$ So, $(b-a)=18+11 = 29$ Hence, the correct answer is 29.
