1.	The number 8,000 is first increased by 20% and then deceased by 20%. Find the resulting number.
Answer» Given: Firstly 8000 is INCREASED by 20%. Secondly 8000 is DECREASED by 20%. To Find: The resulting NUMBER. ANSWER: Given that a number 8000 is firstly increased by 20% and then decreased by 20%. Step 1: To add 20% of 8000 to 8000. Now , 20% of 8000 = 20/100 ×8000. = 1600. → Adding 1600 to 8000 = (8000+1600)= 9600 . Step 2: To subtract 20% of 9600 from 9600. Now , 20% of 9600 = 20/100 × 9600 = 1920. → Subtracting 1920 from 9600 =(9600-1920)=7680 . Hence the required answer is 7680.

The number 8,000 is first increased by 20% and then deceased by 20%. Find the resulting number.

Given:

To Find:

Given that a number 8000 is firstly increased by 20% and then decreased by 20%.

Step 1: To add 20% of 8000 to 8000.

Now , 20% of 8000

= 20/100 ×8000.

= 1600.

→ Adding 1600 to 8000 = (8000+1600)= 9600 .

Step 2: To subtract 20% of 9600 from 9600.

Now , 20% of 9600

= 20/100 × 9600

= 1920.

→ Subtracting 1920 from 9600 =(9600-1920)=7680 .

Hence the required answer is 7680.
