• Mona has Rs.600 with her in Rs.10 and Rs.5 notes .She has four times as many Rs.5 notes as she has Rs.10 notes.

$\qquad \bigstar\large\underline{\orange{\underline\frak{Need \;To\;find: -- }}}$

• How much of each denomination does she have ?

$\qquad \bigstar\large\underline{\blue{\underline\frak{solution: -- }}}$

❍ Let's say, that Rs.10 × x = 10x and Rs.5 × 4x = 20x (as given)  respectively.

$\qquad \underline{\underline{ \bigstar\pmb{ \: According\: to \: the \: question }}}$

$\\ \\ \sf \: \red \leadsto \: 10x + 20x = 600 \\ \\ \sf \red \leadsto \: 30x = 600 \\ \\ \sf \red \leadsto x = \frac{ \cancel{60} \cancel0}{ \cancel3 \cancel0} \\ \\ \qquad \large \boxed{ \red \leadsto \: \frak x =20 } \bigstar$

$\rule{90mm}{0.3mm}$

$\bigstar \fbox{ \boxed{ \text{Therefore \: she \: have \: 20 denomination}}} \bigstar$

Now we get value of x = 20

$\sf{》1x}\\\sf》1(20)\\\large\sf》20$

$\rule{90mm}{0.3mm}$

$\sf》4x\\\sf》4(20)\\\large\sf》60$

Therefore she has 20 notes of Rs.10 and 60 notes of Rs.5
