Answer: Rs. 11,520 
Step-by-step explanation:
As the method of compounding is not stated, the default of simple interest will be used. 
Simple interest is a fixed amount that is paid over the course of the loan and is based on the original amount borrowed. 
Formula is:
Amount owed = Amount borrowed * ( 1 + rate * time)
= 8,000 * ( 1 + 8% * 5.5 years)
= 8,000 * 1.44
= rs 11,520
