Option: a is the correct answer.
a. 222%
We are given a growth factor as:
Growth factor: 1.08 1.12 3.22 1.51
We know that the rate at which the growth increases is denoted by r and is calculated as:
1+r=Growth factor
i.e. r=Growth factor-1
for 1.08 the rate is: 0.08
which in percent is written as: 8%
Similarly the rate of 1.12 is: 12%
Hence, the rate of a growth factor of 3.22 is:
1-3.22=2.22
which in percent is: 222%
Hence, the missing value is: 222%
