If principal = Rs 1,00,000. rate of interest = 10% compounded half yearly. Find

(i) Interest for 6 months.

(ii) Amount after 6 months.

(iii) Interest for next 6 months.

(iv) Amount after one year.

Answer :

Given that, principal(P) = Rs 1,00,000. Rate of interest(R) = 10% compounded half yearly.

We have, Compound interest = Amount - Principal



(i) ( n = 1 for 6 months)




= Rs.1,05,000


⇒∵ Compound interest = A - P


Interest for 6 months = 105000 - 100000


= Rs. 5,000


(ii)Amount after 6 months = Rs.1,05,000 (calculated above)


(iii)For this, P = Amount after 6 months = Rs.1,05,000


( n = 1 for 6 months)




= Rs.1,10,250


⇒∵ Compound interest = A - P


Interest for next 6 months = 110250 - 105000


= Rs. 5,250


(iv) Amount after one year = Rs.1,10,250 (calculated above)
