Question

In year 2013 number of road accident was 10000 traffic police started awareness program to prevent the road accident and found it used by 20% then find out the number of road accident in 2015.​

Answer 1

Answer:

9375

Step-by-step explanation:

accidents (p) = 10000

rate of accident decreased (r)= 20%

time (n) = 2 years

road accident decreased in 2015 = p(1+(r/100))^n

              = 10000(1 - 20/100)^2

= 10000(1/4)^2

= 10000 x 1/16

= 625

therefore road accident of 2015 = 10000 - 625

= 9375
