Question

if 80 is increased to 125 what is the increase percent

Answer 1

Hello Frnd

80 increase to 125, if we want to calculate the % increase, first we need to find how much increase

125 - 80 = 45

Now
Let the % increase be X

80 × X/100 = 45

X/100 = 45/80

X/100 = 0.5625

X = 56.25 %

There is an increase of 56.25%

hope it helps

Answer 2

Let the increase % be X
80+80*X/100 = 125
80(100+X)/100=125
4(100+X)/5=125
And further solve the equation to get the value of X
