Current worth of the investment = [tex]1.2(10^{7} )[/tex]
Worth of the investment 20 years before = [tex]9.6(10^{5} )[/tex]
To find the number of times greater, we have to divide.
Number of times greater = [tex]\frac{current worth}{worth 20 years before}[/tex]
[tex]=\frac{1.2(10^{7} )}{9.6(10^{5} )}[/tex]
[tex]=\frac{1.2(10^{2} )}{9.6}[/tex]
[tex]=\frac{120}{9.6}[/tex]
= 12.5
Hence, the correct option is (b).
