Answer:
Compound space interest
straight A equals straight P open parentheses 1 plus 12 over 100 close parentheses squared
straight I equals straight P open parentheses 1 plus 12 over 100 close parentheses squared minus straight P
Simple space interest
straight I equals fraction numerator straight P cross times 2 cross times 12 over denominator 100 end fraction
Difference equals 72
straight P open parentheses 1 plus 12 over 100 close parentheses squared minus straight P minus fraction numerator straight P cross times 2 cross times 12 over denominator 100 end fraction equals 72
straight P equals 5000 space Rs.
