Correct Answer: C
Solution :
\[\frac{a}{b}=\frac{c}{d}=\frac{e}{f}\] \[\frac{a+c+e}{b+d+f}\] ...(1) Suppose the money becomes 16 times itself in n years \[\frac{a}{b}=\frac{c}{d}\] \[\frac{b}{a}=\frac{d}{c}\] ?..(2) From (1) and (2) \[\frac{a}{b}=\frac{c}{d}\] \[\frac{a}{c}=\frac{b}{d}\] n = 12 years.You need to login to perform this action.
