Option 1: 35
Option 2: 33
Option 3: 23
Option 4: 19
Correct Answer: 35
Solution : Given: A = 1; AND = 19

Question : Simplify $\frac{1}{2 + 2 p} + \frac{1}{2 + 2 q} + \frac{1}{2 + 2 r}$, where $p = \frac{x}{y + z}$, if $q = \frac{y}{z + x}$ and $r = \frac{z}{x + y}$.
Option 1: $1$
Option 2: $x+y+z$
Option 3: $2$
Option 4: $\frac{1}{2}$
Correct Answer: $1$
Solution : Given: $\frac{1}{2+2 p} + \frac{1}{2+2 q} + \frac{1}{2+2 r}$, where $p = \frac{x}{y+z}$, $q=\frac{y}{z+x}$ and $r=\frac{z}{x+y}$ Substitute the values of p, q, and r in the above expression, and we get, $\frac{1}{2+2\times \frac{x}{y+z}} + \frac{1}{2+2\times \frac{y}{z+x}} + \frac{1}{2+2\times \frac{z}{x+y}}$. Now, the first term can be

Question : Three cubes of equal volume are joined end to end. Find the surface area of the resulting cuboid if the diagonal of the cube is $6 \sqrt{3} \mathrm{~cm}$.
Option 1: 509 cm2
Option 2: 504 cm2
Option 3: 516 cm2
Option 4: 512 cm2
Correct Answer: 504 cm2
Solution : Diagonal of cube = $\sqrt{3}$ × side ⇒ $6\sqrt{3}$ = Side × $\sqrt{3}$ ⇒ Side = 6 cm So, length of cuboid, l = 3 × 6 = 18 cm Breadth, b = 6 cm and height, h= 6 cm So, the surface
Question : If $x$,$y$ and $z$ are real numbers such that $(x-3)^2+(y-4)^2+(z-5)^2=0$, then $(x+y+z)$ is equal to:
Option 1: –12
Option 2: 0
Option 3: 8
Option 4: 12
Correct Answer: 12
Solution : Given: $x,y$ and $z$ are real numbers such that $(x-3)^2+(y-4)^2+(z-5)^2=0$ We know, The addition of three perfect squares can be zero only when the individual numbers are zero. So, $(x-3)^2=0, (y-4)^2=0$ and $(z-5)^2=0$ ⇒ $x = 3, y = 4$ and $z = 5$. Then,
