Question

What is the percent increase of 40 to 70

Answer 1

There is 75% increase from 40 to 70

Step-by-step explanation:

Given the two numbers are 40 and 70

The percent increase is calculated by the formula,
`((difference in number))/((base number))*100%`

Where difference is 70 – 40 = 30

Base number is 40

Substituting the values,

Per cent increase =
`(30)/(40)* 100% = 75%`

Therefore, there is 75% increase from 40 to 70

Answer 2

75%

Step-by-step explanation:

• To know the answer, you should take into account that, 70 equals 1,75 times 40.
• This is because
  `(70)/(40)=1,75`.
• Then, if 70 equals 1,75 times 40, it is 0,75 = 75% greater than 40.
