Answer:
Simple interest=4500
maturity value= 10500
Explanation:
Given: Principal P = 6000
Rate % R = 5%
time T = 15 years
we know that simple interest

⇒

on calculating we get SI = 4500
and maturity value = Principal amount + Simple interest
maturity value = 6000+4500 = 10500
hence the final answers are
Simple interest= 4500
and maturity value= 10500
hope this helps!!
