Answer 2

Answer:

= let the no. be 100

= number is increased by 10% = 100 + 10% of 100

= 100 + 10

= 110

Now, the resultant number is reduced by 10%

= the no. obtained is 99

= Decrease in value = 100 - 99 = 1

= percentage decrease = 1 / 100 x 100 = 1%

= Hence , the number is decreased by 1%

= Therefore, the correct is B.
