Given:
The limit problem is:

To find:
The limit of the function by using direct substitution.
Solution:
We have,

Applying limit, we get




Therefore, the correct option is D.
Balance in account cannot be less than
A = P + SI
A-P = SI
5425-5000 = 425
THEREFORE THE SIMPLE INTRESTE IS $425
SI = PTR/100
425 = 5000×1×R/100
425×100/5000×1=R
425×100÷5,000×1 = 8.5%
THEREFORE THE RATE IS 8.5%
