Increase PercentCovid19 has led the world to go through a phenomenal transition . Elearning is the future today. Stay Home , Stay Safe and keep learning!!! When a quantity grows (gets bigger), then we can compute its Increase Percent:
Note: When you compute percent increase you always compare how much a quantity has changed to the original amount. The numerator in these formulas is always a POSITIVE number (or zero, if the quantity doesn't change at all). Examples : 1) The size of a bag that could hold 5 kg of sugar has now been increased so that it can hold 6kg. What is the percentage increase in size? Solution : Old Capacity of the bag = 5 kg New capacity of the bag = 6 kg.
= ( 1 / 5) x 100 = 20 % ________________________________________________________________ 2) The salary of a bank clerk was increased by 7%. If his present salary is $8,025. What was it before increment? Solution : Let the salary before increment be ‘a’ .
7 x a = ( 8025 – a ) x 100 [ cross multiply ] 7a = 802,500 – 100 a ∴ 7a + 100a = 802,500 107a = 802,500 ∴ a = 802,500 / 107 Salary before increment = $7500. ________________________________________________________________ 3) Your friend diets and goes from 125 pounds to 200 pounds. What was her percentage weight gain? Solution : Original weight = 125 pounds New weight = 200 pounds As the weight increase so here we use increase % formula.
= (75 / 125 ) x 100 = (3/5) x 100 = 300 /5 = 60 % So, she gained her weight by 60 %.
