Correct Answer: $30 \frac{5}{9} \%$

Solution : The pie chart represents the distribution of expenditure in degrees. The total expenditure on Labour and Timber is represented by an angle of 110° (65° for Labour and 45° for Timber).
Since the total angle in a circle (or pie chart) is 360°, the percentage of the total expenditure on Labour and Timber can be calculated as follows:
$=\frac{110}{360} \times 100 = 30 \frac{5}{9} \%$
Hence, the correct answer is $30 \frac{5}{9} \%$

Correct Answer: Electrons

Solution : The correct option is Electrons.

Cathode rays are a beam of electrons. They were first observed in the late 19th century in cathode ray tubes, and their discovery played a crucial role in the development of modern physics. The cathode rays are negatively charged particles (electrons) that are emitted from the cathode (negative electrode) in a vacuum tube and travel towards the anode (positive electrode).

Correct Answer: recommends pay revision of central government employees

Correct Answer:

Solution : Because there is no restriction on the rotation of the figure, we will check all possible orientations of the option figures to determine which one may fit in the question figure. By comparison of all the option figures, only the fourth option figure is embedded in the given question figure.

Hence, the fourth option is correct.

Correct Answer: 120

Solution : Given:
The side of a regular hexagon is 5cm.

The perimeter of a given figure(P) = (Total length of the external boundary) + (Total length of the internal boundary)
P = (AB + BC + CD + DE + EF + FG + GH + HI + IJ + JK + KL + LM + MN + NO + OP + PQ + QR + RA) + (ST + TU + UV + VW + WX + XS)
P = (5 + 5 + 5 + 5 + 5 + 5 + 5 + 5 + 5 + 5 + 5 + 5 + 5 + 5 + 5 + 5 + 5 + 5) + (5 + 5 + 5 + 5 + 5 + 5)
P = 90 + 30
P = 120

Therefore, 120 is the perimeter of the given figure. Hence, the third option is correct.

Correct Answer: Circamstances

Solution : The second option is correct.

Circamstances is incorrectly spelled. The error involves replacing "a" with "u". The correct spelling is circumstances, and it means a condition or a state of affairs.

Correct Answer:

Solution : Since the rotation is restricted. So, the embedded figure will have the same orientation as the main figure. By comparison of the question figure with all the option figures, it is evident that the given question figure is embedded only in the third option figure.

Hence, the third option is correct.
