Answer 1

Answer:

answer is 25

Step-by-step explanation:

Given:-

Rakshita has Rs 1 and Rs 2 coins with her.

Total coins are 50

Amount of coins are Rs 75

To find:-

Number of Rs.1 and Rs.2 coins.

Solution:-

Let the number of Rs 1 coins be x and number of Rs 2 coins be y

\begin{gathered}\tt So, \:According\:to\:the \:Question\\\\ \tt the \:total \:number\: of \:coins \: are\:50\\\\ \tt \Rightarrow x+y=50\rightarrow\rightarrow\rightarrow\rightarrow\rightarrow(1)\end{gathered}

So,AccordingtotheQuestion

thetotalnumberofcoinsare50

⇒x+y=50→→→→→(1)

and

\begin{gathered}\tt The \:total \:amount\: of \:coins \: are\:Rs.75\\\\ \tt \Rightarrow x+2y=75\rightarrow\rightarrow\rightarrow\rightarrow\rightarrow(2)\end{gathered}

ThetotalamountofcoinsareRs.75

⇒x+2y=75→→→→→(2)

Solving eq (1) and (2)

\begin{gathered}\tt x+2y=75\rightarrow\rightarrow\rightarrow\rightarrow\rightarrow(2)\\\\\tt x+y=50\rightarrow\rightarrow\rightarrow\rightarrow\rightarrow(1)\\\\\tt By \: solving \:we \:get\:x=25\:and \:y=25\end{gathered}

x+2y=75→→→→→(2)

x+y=50→→→→→(1)

Bysolvingwegetx=25andy=25

So, number of Rs.1 coin= 25

and

number of Rs 2 coins = 25

Answer 2

Answer:

• No of one rupee coins =25
