\small \mathsf{ \color{purple}{Given t = 100  \: T, a = a0/3}}

\small \mathsf{ \color{purp}{Let \:  a’  \: be \:  the \:  amplitude  \: after  \: completing  \: 200  \: oscillations,  \: i.e.  \: at \:  t = 200  \: T.}}

\small \mathsf{ \color{pink}{a = a0/3 = a0e-100Tb}}

\small \mathsf{ \color{pink}{Also, a’ = a0e-200Tb}}

\small \mathsf{ \color{green}{Therefore \: , a’ = a0/9}}

\small \mathsf{ \color{blue}{✦Thus,  \: the \:  ampitude \:  reduces \:  by \:  1/9th  \: of  \: the  \: initial  \: value.✦}}
