Explanation

Electromagnetic spectrum order (longest to shortest wavelength):

Radio waves (includes TV signals) → Infrared → Visible light → X-rays.

It follows this order, starting with television (radio waves) and ending with X-rays.

Explanation

The CPU (Central Processing Unit) is responsible for processing data, not for long-term storage.

Permanent storage is handled by devices like hard drives or SSDs, not the CPU.

Explanation

Let Soomal's age be x.

Saira's age = x + 6

Five years later:

x + 5 + x + 11 = 40

2x + 16 = 40

2x = 24

x = 12

Saira's age = 12 + 6 = 18

Explanation

Let's say the original number is x.

Given:

1/3 of x + 16 = 2 1/3 of x

1/3x + 16 = 7/3x

Multiply both sides by 3:

x + 48 = 7x

48 = 6x

x = 48/6

x = 8

Explanation

"Mr. Imran Khan" is a male, so the correct reflexive pronoun is "himself".

Reflexive pronouns must agree in gender and number with the subject.

Explanation

Valid Methods for Linear Equations:

Substitution: Solve one equation for a variable and substitute into the other.

Elimination: Add/subtract equations to eliminate a variable.

Cramer’s Rule: Uses determinants for systems with unique solutions.

Explanation

If a, b, c ∈ R (real numbers), then:

a < b ⟹ a + c < b + c

This is a fundamental property of inequalities, which states that adding the same value to both sides of an inequality preserves the inequality.

Explanation

Terminating Decimal Definition:

A decimal that ends after a finite number of digits (e.g., 0.5, 0.75).

0.125: Terminates after 3 digits.

Explanation

When two triangles have the same corresponding angles, they are said to be similar.

Similar triangles have the same shape but not necessarily the same size, meaning their corresponding angles are equal and their corresponding sides are proportional.

Explanation

The correct word should be "much" because "water" is an uncountable noun.

"Many" is used with countable nouns (e.g., many bottles of water).

"Much" is used with uncountable nouns (e.g., much water).
