1. For an amount, simple interest at the rate of interest of 12% per annum for 6 years is Rs 25920. What will be the compound interest (in Rs) on same amount at the rate of interest of 8% per annum compounding annually for 2 years?

Let the principal amount = Rs. $$100x$$ Rate of interest = 12% and time period =6 years => $$S.I. = frac{P imes r imes t}{100}$$ => $$frac{100 imes12 imes6}{100}=25920$$ => $$72x=25920$$ => $$x=frac{25920}{72}=360$$ Thus, amount = $$100 imes360=Rs.$$ $$36000$$ $$ herefore$$ Compound interest at the rate of interest of 8% per annum compounding annually for 2 years = $$P[(1+frac{r}{100})^t-1]$$ = $$36000[(1+frac{8}{100})^2-1]$$ = $$36000[(frac{27}{25})^2-1]$$ = $$36000(frac{729-625}{625})$$ = $$57.6 imes104=Rs.$$ $$5990.4$$ => Ans - (D)
