The total cost of 2 books and 4 pen is Rs650. if a cost rs 25 more than a pen , find the cost of each

$\mathtt{\sf{\pink{\LARGE{\boxed{solution-}}}}}$

let the cost of pen is $\sf\green{x }$

$\sf\green{cost\:of\:book\:is\:rs25\:more\:than\: pen }$

so, cost of a book is x + 25

$\mathtt{\sf{\red{\LARGE{\boxed{NoW--}}}}}$

Cost of one pen is $\sf\green{x }$

so, cost of four pen is $\sf\green{4x }$

And

Cost of one book is $\sf\green{x+25 }$

so,cost of 2 books is$\sf\green{(x+25)×2 }$

$\sf\green{2x + 50 }$

$\huge\boxed{\texttt{\fcolorbox{black}{red}{Answer↓}}}$

sum of 4pens and 2books price is$\sf\green{650rs }$

so,

⇨$\sf\green{4x +2x+ 50 = 650}$

⇨$\sf\green{ 6x = 650 - 50 }$

⇨$\sf\green{ x = 600/6}$

⇨$\sf\green{(x = 100 }$

$\mathtt{\sf{\green{\LARGE{\boxed{Hence⛖}}}}}$

cost of one pen is ( x ) = $\sf\green{100}$

and,the cost of one book is $\sf\green{150}$
