Question

During 2003, the production of a factory
decreased by 25%. But, during 2004, it
(production) increased by 40% of what it was
at the beginning of 2004. Calculate the
resulting change increase or decrease) in
production during these two years.​

Answer 1

Answer:

Let at the start of 2003, production = 100

Decrease = 25%

∴ New production = 100 – 25 = 75

In 2004, it is increased by 40%

∴ Increase = (75 × 40)/100 = 30

∴ New production = 75 + 30 = 105

∴ Resulting change in two years (Increase)

= 105 – 100 = 5

∴ Percentage change in increase

= 5/100 × 100 = 5%
