Cost Price (CP) = Rs. 800
Selling Price (SP) = Rs. 1,000

Gain = SP − CP

$$=1000-800=200$$

Gain % = (Gain ÷ CP) × 100

$$=$$200/800​×100

=25%

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 pattern in the series appears to be alternating between adding and subtracting.

27 + 5 = 32

32 - 2 = 30

30 + 5 = 35

35 - 2 = 33

33 + 5 = 38

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%.
