Given ,
- Percentage of money spent = 65%
- Money left = 390$
We need to find ,
Let the total money be [tex]\textsf{\textbf{x}}[/tex]
So now ,
[tex]\sf \longrightarrow ( 100\% - 65\% ) of x = 390 [/tex]
[tex]\sf\longrightarrow \dfrac{35}{100} \times x = 390[/tex]
[tex]\sf\longrightarrow x = 390 \times \dfrac{100}{35}[/tex]
[tex]\sf\longrightarrow \underline{\boxed{\textbf{\textsf{Total\:pocket\:money$=$1114.28}}}}[/tex] $
Hence , his total pocket money was 1114.28 $
