Question

calculate the rate percent per anum if Rs 60000 amounts to Rs79860 in 1.5 years, interest being compounded half yearly.

Answer 1

 Principal = Rs 3000, Rate = 5%, Time = 2 years

(ii) Principal = Rs 3000, Rate =18%, Time = 2 years

(iii) Principal = Rs 5000, Rate = 10 paise per rupee per annum, Time = 2 years

(iv) Principal = Rs 2000, Rate = 4 paise per rupee per annum, Time = 3 years

(v) Principal = Rs 12800, Rate = 712%, Time = 3 years

(vi) Principal =Rs 10000, Rate 20% per annum compounded half-yearly, Time = 2 years

(vii) Principal = Rs 160000, Rate =10 paise per rupee per annum compounded half-yearly, Time = 2 years.

Solution:

Applying the rule A = P(1+R100)n on the given situations, we get:

(i) A = 3000(1+5100)2 = 3000(1.05)2 = Rs 3307.5

Now, CI = A – P = Rs 3307.50 – Rs 3000 = Rs. 307.50

(ii) A = 3000(1+18100)2 = 3000(1.18)2 = Rs 4177.2
