Answer: x³y
Step-by-step explanation: Simple interest is the method to calculate the interest charged on a loan. It is determined by multiplying the principal amount by the interest rate by the number of days elapsing between the payments.
Principal = P = 4x² (Given)
Time = T = 5x (Given)
Rate = R = 5y (Given)
Using the formula of simple interest -
SI = ( PTR )/100
= ( 4x² × 5x × 5y )/100
= ( 4 × 5 × 5 × x² × x × y )/100
= ( 100x³y )/100
= x³y
Therefore, the value of PTR/100 will be x³y.
