Explanation

15% of 15% of 32,000

Step 1: Find 15% of 32,000.

15/100×32000=4800

Step 2: Find 15% of 4,800.

15/100×4800=720

Explanation

If 20% of a = 80% of b

Then:

0.2 x a = 0.8 x b

a = 0.8 / 0.2 x b

a = 4b

So:

a + b = 4b + b = 5b

And in terms of a:

a + b = a + a/4 = 5a/4 = 1.25a

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%.
