Answer 1

Simple interest is a method of calculating the interest charge on a loan and is calculated by multiplying the daily interest rate by the principal by the number of days that elapse between payments.

And Compound interest is the addition of interest to the principal sum of a loan or deposit.

Now, Sum = difference ( 100/r)² 7500

= 12( 100/r)² 7500/120000

= 1/r² 0.0625

= 1/r² r²=16 taking under root √r²= √16 r= 4%
