Explanation

Given sequence: 4, 11, 7, 14, 10, 17, __, 20

Two alternating series are used:

First series: 4 → 7 → 10 → 13 (+3 each time)

Second series: 11 → 14 → 17 → 20 (+3 each time)

Missing number: 13

Explanation

Given:

Increment in number = 20% of the number

Decrement in number = 20% of the new number

Concept used:

Net increase or decrease percent = {(Original number or Final number) - (Final number or original number) ÷ Original number} × 100

Calculation:

Let the original number be 100

When the number is increased by 20%

New Number = 100 + 20% of 100

⇒ 100 + 20

⇒ 120

Now, the number is decreased by 20%

Final number = New number – 20% of new number

⇒ 120 – 20% of 120

⇒ 120 – 24

⇒ 96

∴ Net Decrease in percentage = { (100 – 96) / 100} × 100

⇒ {4/100} × 100

⇒ 4%

∴ The net decrease percentage is 4%.

Explanation

Find the differences:

6 − 2 = 4

12 − 6 = 6

20 − 12 = 8

30 − 20 = 10

42 − 30 = 12

The differences increase by 2 each time.

Next difference = 14

42+14=56

Explanation

NOTE:

• If the question only says “all four sides are equal,” then the correct answer is a rhombus.
• If the question says “all four sides are equal, and all four angles are right angles (90°),” then the correct answer is Square.
• Example:
• Diamond shape ◇ = Rhombus
• Box shape □ = Square

Explanation

The decimal number is 11.

Binary uses only 0 and 1.

11 = 8 + 2 + 1.

Binary place values: 8, 4, 2, 1.

Therefore, 11₁₀ = 1011₂.
