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 the total increase will be 44%.
(you can choose any number and calculate) according to the above solution
