Answer 1

Answer:

Production of scooters rose to 48400 from 40000

Rate of growth is 10%

so in first year growth will be=(40000+  

100

10

​  

×40000)

                                                        =44000 scooters

in the second year growth will be=(44000+  

100

10

​  

×44000)

                                                       48400 scooters

Time required for the growth from 40000 to 48400 is 2 years

Answer 2

Answer:

20%

Step-by-step explanation:

r =x

P= 40000

A= 57600

40000×(1+x/100)^2 = 57600

(1+x/100)^2 = 57600/40000

(take root)

(1+x/100)^2 = (24/20)^2

1+x/100 = 24/20

x/100 = 24/20-1

x/100 = 4/20

x = 4/20×100

x = 20%
