Question

Increase 2000 by 10% and then decrese the amount by 10%​

Answer 1

Step-by-step explanation:

Hi,

10℅ of 2000 = 10/100 × 2000 = 20 × 10 = 200.

Now , added 200 to 2000.

=> 2000 + 200 = 2200

Subtract 200 from 2200.

=> 2200 - 200 = 2000.

So, Answer remains the same .

Answer 2

2000 incrsd by 10%

2000+{2000×10%}

=2000{2000 ×10/100}

=2000+200=2200

then decreased by 10%

=2200-{2200×10%}

=2200-{2200×10/100}

=2200-{220}

=2200-220

=1980
