Question

Rakshita has only Rs. 1 and Rs. 2 coins with her. If the total number of coins that she has
is 50 and the amount of money with her is Rs 75, then the number of Rs.1 andRs.2 coins
is, respectively____________.NEED CORRECT EXPLANATION.GIVING 25P

Answer 1

Answer:

Let us take,

Re.1 coins as x

Rs. 2 coins as y

The total number or Re.1 and Rs.2 are 50

So x+y=50_______________________________(1)

Therefore, the total amount of Re.1 is 1x

Therefore, the total amount of Rs.2 is 2y

Total money is 75

Hence the sum of Total Re.1 amount + Total Rs.2 amount = 75

This is 1x+2y=75  ______________________________(2)

Equating Eqn. 1 and 2

x=50-y

Putting x in 1x+2y=75  

1(50-y)+2y=75  

y=25

Putting y in  x=50-y

We get x = 50 – 25 = 25  

Therefore, the number of Re.1 coin is 25 and Rs.2 coin is 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 eq (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
