Answer:
8%
Step-by-step explanation:
Let the number is 100
If it Increased 20% then
100 × 20 ÷ 100 = 20
Increased number is 100 + 20 = 120
Now it will decrease 10 % then
120 × 10 ÷ 100 = 12
Decreased number is 120 - 12 = 108
Now
108 - 100 = 8
It means that 100 increased 8.
Increased present is 8 %

Answer:
Net increase percent = 8%
Step-by-step explanation:
Let the no. be 100
20% of 100 = 20/100×100 = 20
Increase in no. = 100+20 = 120
10% of 120 = 10/100×120 = 12
Decrease in no. = 120-12 = 108
108>100
Hence, the no. is increased by 8
Net increase percent = 8/100×100 = 8%
