Correct Answer: interrupt

Solution : The correct choice is the third option.

Explanation: "Interrupt" is the base form of the verb, and it is used to make a general request or command not to disrupt someone while he/she is speaking. Since this is an imperative sentence, the base form of

Correct Answer: 3440 cm

Solution : Given: The pole is 9030 cm long.
The sum of the ratios of the lengths of the saffron, white, and green portions is 6 + 7 + 8 = 21
The length of the green portion of the pole = $9030\times \frac{8}{21} = 3440\

Correct Answer: $\cos A-\sin A$

Solution : $\frac{\cos A}{1+\tan A}-\frac{\sin A}{1+\cot A}$
$=\frac{\cos A}{1+\frac{\sin A}{\cos A}} - \frac{\sin A}{1+\frac{\cos A}{\sin A}}$
$=\frac{\cos^2 A}{\cos A + \sin A} - \frac{\sin^2 A}{\sin A + \cos A}$
$=\frac{\cos^2 A - \sin^2 A}{\sin A + \cos A}$
$=\frac{(\cos A + \sin A)(\cos A -

Correct Answer: Effervescence

Solution : The correct option is Effervescence.

A liquid will produce bubbles when air is introduced, which causes a bubble to develop. This process is known as effervescence because effervescence is the discharge of gas from an aqueous solution and as a result foaming or freezing

Correct Answer: $\frac{1}{2}(a–1)$

Solution : Given: $2x=\sqrt{a}+\frac{1}{\sqrt{a}}, a>0$
$⇒2x=\sqrt{a}+\frac{1}{\sqrt{a}}$
$⇒x=\frac{1}{2}(\sqrt{a}+\frac{1}{\sqrt{a}})$
Calculating the value of ${\sqrt{x^{2}-1}}$
$⇒{\sqrt{x^{2}-1}}={\sqrt{(\frac{1}{2}(\sqrt{a}+\frac{1}{\sqrt{a}}))^{2}-1}}$
$⇒{\sqrt{(\frac{a^2-2a+1}{4a})}}=\frac{a-1}{2\sqrt{a}}$
So that $\frac{\sqrt{x^{2}-1}}{x-\sqrt{x^{2}-1}}$ becomes
$⇒\frac{\sqrt{x^{2}-1}}{x-\sqrt{x^{2}-1}}=\frac{\frac{a-1}{2\sqrt{a}}}{\frac{1}{2}(\sqrt{a}+\frac{1}{\sqrt{a}})-(\frac{a-1}{2\sqrt{a}})}$
$⇒\frac{\sqrt{x^{2}-1}}{x-\sqrt{x^{2}-1}}=\frac{a-1}{2\sqrt{a}}×\frac{2\sqrt{a}}{2}=\frac{1}{2}(a–1)$
Hence, the correct answer is $\frac{1}{2}(a–1)$.

Correct Answer: Fluorine

Solution : The correct option is Fluorine.

The element that was arbitrarily assigned a value of 4.0 in the 'Halogens' section by Linus Pauling in 1922 is Fluorine (F). This assignment of this value to Fluorine was part of Linus Pauling's efforts to develop the concept

Correct Answer: Ice : Freeze

Solution : Given:
Fire : Burn :: ? : ?

When a fire occurs, it results in burns.
Similarly, when something becomes ice, it results in freezing.

Hence, the third option is correct.

Correct Answer: Ethylene

Solution : The correct option is Ethylene.

Ethylene is a gas that is widely used to artificially ripen green fruit. Ethylene is a naturally occurring plant hormone that regulates fruit ripening. It is also utilised in the commercial ripening of fruits. The fruits themselves create ethylene gas.

Correct Answer: 22

Solution : Meenu's present age = 38 years
Daughter's present age = 8 years
Let be the after $x$ number of years from the present year for Meenu's age be twice of that of her daughter's age.
$\therefore$ $38+x=2(8+x)$
⇒ $38-16=x$
⇒ $x=22$ years
Hence, the correct
