i think the answer to this is Rs 10680...though i m not too good at maths....

note- i have calculated interest and amount both upto 12th year and for the 13th year as u have asked one year after i have taken into account only the intreset amount.....

500*12+39000*12/100

 

500 is the principal for 12 years (i assumed that 13th year only intrest accrued and no princiapal was deposited)

 

39000 in the way that - for the first year no interest 

2nd year - interest on500 @ 12 %

3 rd year- Intt on1000 @ 12%

 

and so on

 

Pardon me!! I took the interest @ 12%....

The formula for Future Value of Annuity is : F.V =  Annuity x ( ( ( 1 + (R.O.I) ) ^ T - 1) / R.O.I)

R.O.I is 10%

Annuity is 500

Time is 12 years

Therefore on substituting : F.V of Annuity would be = Rs. 10692.14

but interest for the year after the 12th investment will also have to be added which would come to 1069.214 @ 10% p.a

Therefore amount standing to his credit would be = Rs. 11761.36
