'P' is a variable such that if 20% of it is added to its one-fifth then the result is equal to 12 subtracted from seven tenths of p. What is the value of p? 

 প্রশ্নে বলা হচ্ছে, 20% P এর সাথে যদি P/5 যোগ করা হয় তবে ফলাফল হবে \((\frac{{7p}}{{12}} - 12)\) . p এর মান বের করতে হবে । 

 দেয়া আছে, 20% of p = \(\frac{{20p}}{{100}} = \frac{p}{5}\) 

   প্রশ্নমতে, \(\frac{p}{5} + \frac{p}{5} = \frac{{7p}}{{10}} - 12\) 

      => \(\frac{{2p}}{5} = \frac{{7p - 120}}{{10}}\) 

      => 2p = \(\frac{{7p - 120}}{2}\)

     => 7p - 120 = 4p 

    => 7p - 4p = 120 

    => 3p = 120  

     =>  P = 120/3 

            P = 40
