​

Answer 1

Answer:

44%

Step-by-step explanation:

Suppose original number is 100.

It is increased by 20 %, so result will be 120.

The resulting number is again increased by 20%, that is increased by 120 *20/100, that is increased by 24. The final result will be 120+24 that is 144.

The final result is increased by 44 compared to original number 100.

So increase by 44%.

Answer 2

Answer:

4%

Step-by-step explanation:

The increase is=20%

The number further decreases by=20%

Let us imagine the number as 100

So increase on 100 by 20%=20

so the number is 120

If we further decrease the number by 20%

it will be 20% less than 120  

 

ie.24  

so the answer is 96  

 

so, the number is decreased by 4%
