$\green{\underline \bold{Given :}}$

$\:\:$

• Bag contain 25 paise and 50 paise coins.

• Number of 25 paise coin is thrice the number of 50 paise coins

• Total amount is 120 Rs

$\:\:$

$\red{\underline \bold{To \: Find:}}$

$\:\:$

• Number of each type of coin.

$\:\:$

$\large{\orange{\underline{\tt{Solution :-}}}}$

$\:\:$

Let number of 25 paise coins be 'x'

Let number of 50 paise coins be 'y'

$\:\:$

$\purple{\underline \bold{According \: to \: the \ question :}}$

$\:\:$

$\sf 1Rs \: = \: 100\: paise$

$\:\:$

$\sf \longmapsto 25x + 50y = 12000$

$\:\:$

$\underline{\bold{\texttt{Dividing the above equation by 25}}}$

$\:\:$

$\sf \longmapsto x + 2y = 480$ -----(1)

$\:\:$

Also,

$\:\:$

$\sf \longmapsto x = 3y$ -------(2)

$\:\:$

$\underline{\bold{\texttt{Putting x = 3y in (1)}}}$

$\:\:$

$\sf \longmapsto 3y + 2y = 480$

$\:\:$

$\sf \longmapsto 5y = 480$

$\:\:$

$\sf \longmapsto y = \dfrac { 480 } { 5 }$

$\:\:$

$\sf \longmapsto y = 96$

$\:\:$

$\underline{\bold{\texttt{Putting y = 96 in (2)}}}$

$\:\:$

$\sf \longmapsto x = 3(96)$

$\:\:$

$\sf \longmapsto x = 288$

$\:\:$

Hence number of 25 paise coins is 288

Number of 50 paise coins is 96

$\rule{200}5$
