Answer 2

Answer:

1% decrease

Step-by-step explanation:

Let the original number be 100.

Increase = 10% = 10/100 × 100 = 10

Number after increasing = 100+10 = 110

Decrease = 10% = 10/100 × 110 = 11

Number after decreasing = 110-11 = 99

100 > 99.

Decrease in number = 100 - 99 = 1

Percentage decrease = 1/100 × 100 = 1%
