e) none of these

Let the numerator = $x$

=> Denominator = $(3x+2)$

Fraction = $\frac{x}{3x+2}$

If the numerator as well as denominator are increased by one

=> $\frac{x+1}{3x+2+1}=\frac{1}{3}$

=> $\frac{x+1}{3x+3}=\frac{1}{3}$

=> $3x+3=3x+3$

It cannot be solved, thus $x$ can take any value and the fraction can be 2/8 , 3/11 , 4/14 ,….

=> Ans – (E)

Expression : $\frac{?}{24}=\frac{72}{\sqrt{?}}$

=> $(?)^{(1+\frac{1}{2})}= 72 \times 24$

=> $(?)^{\frac{3}{2}} = 1728 = 12^3$

Multiplying exponents by $(\frac{2}{3})$ on both sides

=> $(?)^{(\frac{3}{2} \times \frac{2}{3})}= (12)^{(3 \times \frac{2}{3})}$

=> $(?)=12^2=144$

=> Ans – (D)

Let the number be $x$

According to ques, => $x-48=\frac{x}{3}$

=> $3x-144=x$

=> $3x-x=2x=144$

=> $x=\frac{144}{2}=72$

$\therefore$ $(\frac{2}{3})^{rd}$ of number = $\frac{2}{3} \times 72$

= $2 \times 24 = 48$

=> Ans – (D)

Expression : $(299.99999)^{3}$ =?

$\approx (300)^3$

= $2,70,00,000$

=> Ans – (A)

Let the 3 consecutive numbers be $(x-1),(x),(x+1)$

Difference between first and third number = $(x+1)-(x-1)$

= $(x-x)+(1+1)=2$

=> Ans – (D)

Expression : $0.001+9.909\times1.01\div0.1$

= $0.001 + \frac{9.909 \times 1.01}{0.1}$

= $0.001 + (10.00809 \times 10)$

= $0.001 + 100.0809 = 100.0819$

Expression = $4275\div496\times(21^{2})$=?

= $\frac{4275}{496} \times 441$

= $8.62 \times 441 = 3801.42$

$\approx 3800$

Let the number be $x$

According to ques,

=> $x^2-78^2=6460$

=> $x^2=6460+6084$

=> $x=\sqrt{12544}=112$

=> Ans – (E)

We need to find the approximate value of $\sqrt{4321} \approx$ 65.73

We find that $65^2=4225$ < $4321$ and $66^2=4356$ > $4321$

So the least number to be added = 4356 – 4321 = 35

$\therefore$ 35 can be added to 4321 to make it a perfect square.

=> Ans – (E)

Let the successive natural numbers be $(x),(x+1)$

Product = $x(x+1)=8556$

=> $x^2+x-8556=0$

=> $x^2+93x-92x-8556=0$

=> $x(x+93)-92(x+93)=0$

=> $(x+93)(x-92)=0$

=> $x=-93,92$

$\because$ The numbers are natural, thus $x \neq -93$

$\therefore$ Smaller number = $x=92$

=> Ans – (D)
