[tex]Let P=Rs.x
\\ A=Rs.2x[/tex]
[tex] \therefore \: SI = Rs.x[/tex]
[tex]SI = \frac{PTR}{100} [/tex]
[tex]x = \frac{x \times T \times 122 }{100} [/tex]
[tex]T = \frac{25}{3} year[/tex]
[tex] \implies{ \boxed{ \underline{8year \: 4months}}}[/tex]

[tex]LetP=Rs.xA=Rs.2x
\therefore \: SI = Rs.x∴SI=Rs.x
SI = \frac{PTR}{100}SI=100PTR
x = \frac{x \times T \times 122 }{100}x=100x×T×122
T = \frac{25}{3} yearT=325year
\implies{ \boxed{ \underline{8year \: 4months}}}⟹8year4months
