Answer:
0.08% increase.
Step-by-step explanation:
Let the no. be 100
Then when increased by 20% , it becomes 120 .
When it (120) is decreased by 10% , it becomes 120 - ( 0.1 × 120 ) = 108
Net increase or decrease = ( Final no. - Initial no. ) ÷ 100
= (108 - 100) ÷ 100
= 8÷100
= 0.08%
Since it is positive value , therefore, no. is increased by 0.08%.
