A number is increased by 40% and then decreased by 25%.what is the net percentage increase/decrease in the number? About the author Brielle
lets say 100 is increased by 40% = 100+ (40/100)×100 = 140 Now 25% is decreased from 140 140- (25/100)× 140 = 140-35 = 105 So 100 is changed into 105 increased= 105-100= 5% Reply
Answer:
the number will increase by 15%
lets say 100 is increased by 40%
= 100+ (40/100)×100
= 140
Now 25% is decreased from 140
140- (25/100)× 140
= 140-35
= 105
So 100 is changed into 105
increased= 105-100= 5%
