16

Step-by-step explanation:

9/12=12/x

x=16

We have the following exponential equation:
 y = A (b) ^ n
 Defined the following variables:
 A: is the initial number of customers who applied
 b: is the rate of increase in the number of people who applied every month
 n: is the number of months since the bank opened
 Substituting values we have:
 y = 27 (1.2) ^ 4
 y = 27 * 2.07
 
 There are 2.07 more people in month 4 than in month 1
