Answers & Solutions:

1) Answer (B)

Expression : $\frac{(243)^\frac{n}{5}3^{2n+1}}{9^{n}3^{n-1}}$

= $\frac{(3^5)^\frac{n}{5}\times3^{2n}\times3}{3^{2n}\times3^{n}\times3^{-1}}$

= $\frac{3^{n+2n}\times3}{3^{n+2n}\times3^{-1}}$

= $\frac{3^{3n}}{3^{3n}}\times3\times\frac{1}{\frac{1}{3}}$

= $3\times3=9$

=> Ans – (B)

2) Answer (A)

Given : $3x^2+5x+3=0$

Divide by $x$, => $3x+\frac{3}{x}=-5$

=> $x+\frac{1}{x}=\frac{-5}{3}$ ————-(i)

Cubing both sides, we get :

=> $(x+\frac{1}{x})^3=(\frac{-5}{3})^3$

=> $x^3+\frac{1}{x^3}+3(x)(\frac{1}{x})(x+\frac{1}{x})=\frac{-125}{27}$

=> $x^3+\frac{1}{x^3}+3(1)(x+\frac{1}{x})=\frac{-125}{27}$

=> $x^3+\frac{1}{x^3}+3(\frac{-5}{3})=\frac{-125}{27}$

=> $x^3+\frac{1}{x^3}=\frac{-125}{27}+5$

=> $x^3+\frac{1}{x^3}=\frac{-125+135}{27}$

=> $x^3+\frac{1}{x^3}=\frac{10}{27}$

=> Ans – (A)

3) Answer (C)

Let edge of cube be $2a$ cm and thus diameter of sphere = $2a$ cm

=> Radius of sphere = $\frac{2a}{2}=a$ cm

Volume of cube = $(2a)^3=8a^3$ $cm^3$ ———–(i)

Volume of sphere = $\frac{4}{3}\pi r^3$

= $\frac{4}{3} \pi \times(a)^3=\frac{4a^3\pi}{3}$ $cm^3$ ———–(ii)

Dividing equation (i) by (ii), we get :

=> Required ratio = $\frac{8a^3}{\frac{4a^3\pi}{3}}$

= $\frac{8\times3}{4\pi}=\frac{6}{\pi}$

$\therefore$ Ratio of the volume of a cube to that of a sphere which will fit inside the cube = $6:\pi$

=> Ans – (C)

4) Answer (A)

String of length 24 cm is bent into square, => Perimeter of square = 24 cm

Let side of square = $a$ cm

=> $4a=24$

=> $a=\frac{24}{4}=6$ cm

Let the other side of triangle be $b$ and hypotenuse be $c$ cm

=> Perimeter of triangle = $a+b+c=24$

=> $b+c=24-6=18$

=> $c=18-b$ ————(i)

Also, using Pythagoras Theorem

=> $6^2+b^2=c^2$

=> $c^2-b^2=36$ ———–(ii)

Solving equations (i) and (ii), we get : $b=8$ cm and $c=10$ cm

$\therefore$ Area of triangle = $\frac{1}{2} ab$

= $\frac{1}{2}\times6\times8=24$ $cm^2$

=> Ans – (A)

5) Answer (C)

Original count = 40,000

In the next 2 hours, it increases by 10%

=> Blood cell count after 2 hours = $40,000(1+\frac{10}{100})^2=40,000(\frac{11}{10})^2$

= $40,000\times\frac{121}{100}=48,400$

It decreases by 10% in next hour

=> Blood cell count after 3 hours = $48,400(1-\frac{10}{100})^1$

= $48,400\times\frac{9}{10}=43,560$

It remains constant in the next hour, => Blood cell count after 4 hours = $43,560$

In the next 2 hours, it increases by 5%

=> Blood cell count after 6 hours = $43,560(1+\frac{5}{100})^2=43,560(\frac{21}{20})^2$

= $43,560\times\frac{441}{400}=48,024.9\approx48,025$

=> Ans – (C)

6) Answer (C)

Principal sum = Rs. 5000

Rate of interest = 8% and time period = $\frac{9}{12}=\frac{3}{4}$ years

Compound interest when interest is compound quarterly = $P[(1+\frac{R}{400})^{4T}-1]$

= $5000[(1+\frac{8}{400})^{\frac{3}{4}\times4}-1]$

= $5000[(1+\frac{1}{50})^3-1]$

= $5000[(\frac{51}{50})^3-1]$

= $5000\times(\frac{132651-125000}{125000})$

= $\frac{7651}{25}=Rs.$ $306.04$

=> Ans – (C)

7) Answer (C)

Length of the arc if it subtends x degrees at the center is $\frac{x}{360}\times2\times\pi\times r$
Here x=45 degrees
Required ratio= $\frac{\frac{45}{360}\times2\times\pi\times r}{2r}$

8) Answer (A)

Given 2(l+b)=24
Given b=diagonal of square
d=8 cm
b=8 cm
l=4 cm
Area of the rectangle=l*b
=32 sq cm

9) Answer (D)

In a triangle internal angular bisector divides the opposite side in the ratio of other sides.
Therefore AB/AC=BE/EC
BE=3 cm
=10 cm
