Explanation

Let the total number of boys be$x$.

45% of $x$ participated: $0.45\times x=135$.

Solve for $x$: $x=\frac{135}{0.45}$

$x=300$, so the total number of boys is 300.

Explanation

S-waves are transverse seismic waves.

They cause particles to move perpendicular to the direction of wave propagation.

S-waves cannot pass through liquids or gases because these cannot support shear stress.

They only travel through solids, like the Earth’s crust and mantle.

This property helps scientists study the internal structure of Earth.

Explanation

Original length = 72 cm, stretched length = 90 cm.

Increase in length = 90 − 72 = 18 cm.

Percentage increase = (Increase ÷ Original length) × 100.

Percentage increase = (18 ÷ 72) × 100 = 25%.

Therefore, the rope’s length increased by 25%.

When milk reaches the processing plant, it is poured into silos for storage.

Silos are large containers that keep milk fresh and uncontaminated.

They allow controlled temperature to prevent spoilage.

From silos, milk is later processed for pasteurization, packaging, and distribution.

Using silos ensures efficient storage and handling in the dairy industry.
