The difference between the Simple Interest and the Compound Interest on a sum of money for 3 years at 10% per annum$=$ Rs. 558. To find : We have to find the sum. Solution : Let the sum be P. Compound interest $=P[(1+\frac{r}{100})^n - 1]$ $=P[(1+\frac{10}{100})^3 - 1]$ $=P[(1+\frac{1}{10})^3 - 1]$ $=P[(\frac{11}{10})^3 - 1]$ $=P[\frac{1331}{1000} - 1]$ $=P[\frac{1331 - 1000}{1000}]$ $=P[\frac{331}{1000} ]$ Simple interest $= \frac{P \times n \times r}{100}$ $= \frac{P \times 3 \times 10}{100}$ $= \frac{3}{10}P$ $CI - SI = 558$ $\frac{331}{1000}P - \frac{3}{10}P = 558$ $\frac{331}{1000}P - \frac{3 \times 100}{10 \times 100}P = 558$ $\frac{331}{1000}P - \frac{300}{1000}P = 558$ $ \frac{31}{1000}P=558$ $ P = \frac{558 \times 1000}{31}$ $P = 18 \times 1000 = 18000$ Therefore, the sum is ₹18000.
