Correct Answer: GWH

Solution : Given:
AZB : CYD :: EXF : ?

Add 2 to the place value of the first and third letters, and subtract 1 from the place value of AZB to get the related letter cluster.
A + 2 = C; Z – 1 = Y;

Correct Answer: $\frac{1}{2}$

Solution :
We have,
$\Delta$QBC$\sim\Delta$PAC
Since ABCD is a square,
AB = BC = CD = DA
In $\Delta$ABC,
$ ⇒AC=\sqrt{(AB)^2+(BC)^2}$
$⇒ AC=\sqrt{(2BC)^2}$
$⇒AC=\sqrt{2}BC$
In similar triangles, the ratio of their areas is equal to the square of the ratio of their corresponding sides.
$⇒\frac{\text{Area of $\Delta$QBC}}{\text{Area

Correct Answer: Fluorine

Solution : The correct answer is Fluorine.

An oxidising agent is a substance that oxidises other elements. They aid the other elements in losing their electrons, increase their oxidation states, and themselves gain electrons. Elements with high electronegativity are particularly good oxidising agents, like fluorine, oxygen

Correct Answer: 24

Solution : Given: Howrah to Bandel at an average speed of 20 km/h and returns at an average speed of 30 km/h.
Applying the formula for average speed = $\frac{2xy}{x+y}$
= $\frac{2×20×30}{20+30}$
= $\frac{1200}{50}$
= 24 km/h.
Hence, the correct answer is 24 km/h.

Correct Answer: 55°

Solution : As $\triangle ABC \cong \triangle PQR$, then
$\angle A = \angle P$
In $\triangle PQR$, from the angle sum property of a triangle, we can write
$\angle P + \angle Q + \angle R = 180°$
$⇒\angle P + 35°+ 90°= 180°$
$⇒\angle P =

Correct Answer: Meagre

Solution : The correct choice is the third option.

The most appropriate antonym for copious in the given sentence is meagre because copious refers to something that is in large amounts, while meagre means in small amounts.

The meanings of the other options are as follows:

Correct Answer: $\frac{4}{7}$

Solution : Given: $x+\frac{2}{x}=1$
Now, $\frac{x^2+7 x+2}{x^2+13 x+2}$
Taking $x$ as common from the numerator and the denominator, we get,
$\frac{x(x+7 +\frac{2}{x})}{x(x + 13 + \frac{2}{x})} = \frac{1 + 7}{1 + 13} = \frac{8}{14} = \frac{4}{7}$
Hence, the correct answer is $\frac{4}{7}$.

Correct Answer: $2^{75}×10^{25}$

Solution : Given: $10^{100}$ is divided by $5^{75}$.
= $\frac{10^{100}}{5^{75}}$
= $\frac{(2×5)^{100}}{5^{75}}$
= $\frac{2^{100}×5^{100}}{5^{75}}$
= $2^{100}×\frac{5^{100}}{5^{75}}$
By using, $\frac{a^{m}}{a^{n}}=a^{(m–n)}$
= $2^{100}×5^{(100-75)}$
= $2^{100}×5^{25}$
= $2^{75}×2^{25}×5^{25}$
= $2^{75}×10^{25}$
Hence, the correct answer is $2^{75}×10^{25}$.
