​

Answer 1

Answer:

D. 25 and 25

Step-by-step explanation:

Acc to question

let 1 rupee con as x

and 2 rupee coin as y

x+y = 50

y= 50-x

again acc to question

let 1 rupee coin as x

and 2 rupee coin as 2x

so x+2x=75

3x=75

so x= 25---------------2

using 2in 1 we get

y=50-25

y=25

so x=25

y=25

Answer 2

Your Answer

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

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

and

$\tt The \:total \:amount\: of \:coins \: are\:Rs.75\\\\ \tt \Rightarrow x+2y=75\rightarrow\rightarrow\rightarrow\rightarrow\rightarrow(2)$

Solving equation (1) and (2)

$\tt x+2y=75\rightarrow\rightarrow\rightarrow\rightarrow\rightarrow(2)\\\\\tt x+y=50\rightarrow\rightarrow\rightarrow\rightarrow\rightarrow(1)\\\\\tt By \: solving \:we \:get\:x=25\:and \:y=25$

So, number of Rs.1 coin= 25

and

number of Rs 2 coins = 25
