<u>Answer:</u>
75
<u>Step-by-step explanation:</u>
We are given that 80 is increased by 25% and then decreased by 25% so we are to find the final value.
Increase of 25% in 80 = 25% of 80
= 25/100 × 80
= 20
So our new value after 25% increase = 80 + 20 = 100
Now this new value is decreased by 25% = (100 - 25)% of 100
= 75/100 × 100
= 75
Answer:
See below.
Step-by-step explanation:
Increases by 25% :- it is 80 * 1.25 = 100.
100 decreased by 25% = 100 * 0.75
= 75.
