a person has 1&2 rupee coins with him
total amount with him is 75.total number of coins with him is 50.find how many 1&2 rupee coinsare there with him.
Solve these two equations for x and y:
x + y = 50
x + 2y = 75
(y is the number of 2 rupee coins; x is the number of 1 rupee coins)
Clearly y = 25, and x is also 25.
he has 25 one rupee coins and 25 two rupee coins together he has 50 coins with total amount of 75 rupees
1*25+2*25=25+50=75 rupees
To find the number of 1 and 2 rupee coins a person has, given the total amount and the total number of coins, we can solve a system of linear equations.
Let's assume:
x = number of 1 rupee coins
y = number of 2 rupee coins
We can set up two equations based on the given information:
1. The total amount equation: 1x + 2y = 75
2. The total number of coins equation: x + y = 50
Now, we can solve this system of equations using any method such as substitution or elimination.
Let's solve it using the substitution method:
From equation 2, we can rewrite it as x = 50 - y.
Substitute this value of x into equation 1:
1(50 - y) + 2y = 75
50 - y + 2y = 75
50 + y = 75
y = 75 - 50
y = 25
Now substitute the value of y back into equation 2 to find x:
x + 25 = 50
x = 50 - 25
x = 25
Therefore, there are 25 one-rupee coins and 25 two-rupee coins with the person.
