Question

8. Find the per cent increase or decrease in the following:
(a) The salary of a man is changed from 800 to 850.
The answer is 6 1/4 percent but how​

Answer 1

Answer:

it is 6 1/4

because increase or decrease percentage = change upon original × 100

so change = 850 - 800 = 50

so, 50/800 × 100

= 50/8 = 25/4 = 6 1/4%
