Elina develops the customer details maintenance application and the EMI calculator application
and provides both the applications to Dwayne for testing. While testing the applications, Dwayne
discovers the following problems:
The application displayed a message to the user to enter the path of the customer details file.
However, the customer details maintenance application crashed as Dwayne mistakenly entered
the wrong file path. Therefore, he asks Elina to modify the application so that it does not crash
due to similar errors. Modify the code that Elina needs to accomplish the preceding task. [5

The EMI calculator application crashed when Dwayne accidentally entered zero as the rate of
interest. Therefore, he asks Elina to modify the application so that it displays an error message
if the principal amount, rate of interest, or tenure of the loan entered is invalid. Add the code
snippet that Elina should use to modify the application according to the preceding requirements.

Dwayne often needs to calculate the amount of Emulated Monthly Installment (EMI) that needs to
be charged from a particular person. The EMI is calculated according to the following formula:
EMI = Principal loan amount×Rate of interest×(1 + Rate of interest)Tenure of loan in months/((1 +
Rate of interest)Tenure of loan in months - 1)
The rate of interest is calculated on a monthly basis. For example, if the rate of interest is 12 % per
annum, it is calculated as (12/100)/12.
Dwayne manually calculates the interest rate using a calculator. However, he often commits
mistakes in calculating the interest due to the complex formula. Therefore, he asks Elina to build
an application that accepts the principal loan amount, rate of interest, and tenure of the loan and
calculates the EMI amount. Write the code that Elina should implement to create the application.
