Correct Answer:

Solution : Since there is a restriction on the rotation of the figure, we will check where the question figure can exactly fit itself in the given option figures.
By comparison of all the option figures, the given question figure is embedded only in the third option figure.

Hence, the third option is correct.

Correct Answer: 20 percent

Solution : According to the question,
Marked Price = 150% of cost price
$\therefore$ $\text{MP} = 1.5\text{C}$
After a 20% discount, the selling price (SP) is given by:
SP $=$ Marked Price $−$ Discount
⇒ SP $=1.5\text{C}−0.2\times1.5\text{C}=1.2\text{C}$
⇒ Profit $=$ SP $−$ CP $=1.2\text{C}−\text{C}=0.2\text{C}$
Profit Percentage = $\frac{\text{Profit}}{\text{Cost Price}}\times 100$
$=\frac{0.2\text{C}}{C}\times 100$%
⇒ Profit Percentage = 20%
Hence, the correct answer is 20 percent.

Correct Answer: 4

Solution : Given: $2x+3y=k$
If (2, 0) is a solution of the linear equation $2x+3y=k$
Putting $x = 2$ and $y = 0$ to get:
⇒ $2(2)+3(0) = k$
$\therefore k = 4$
Hence, the correct answer is 4.

Correct Answer: Energy

Solution : The correct answer is Energy.

Planck's constant (ℎ) has dimensions of energy multiplied by time. In terms of units, it is commonly expressed in joule-seconds (J·s) in the International System of Units (SI). It can be expressed as [ℎ] = [E] × [t] where:

[ℎ} is the dimension of Planck's Constant,
[E] is the dimension of energy,
[t] is the dimension of time.
