Given:
- Selling 6 radios + 4 televisions = Rs. 18,480
- Selling 14 radios + 2 televisions = Rs. 18,480
To find:
- Price of 1 television
Solution:
Let the cost of 1 radio be x and the cost of 1 television be y.
From the given information, we can form the following equations:
6x + 4y = 18,480 ...(1)
14x + 2y = 18,480 ...(2)
We need to find the value of y.
Method 1: Using elimination method
Multiplying equation (1) by 7 and subtracting it from equation (2) multiplied by 3, we get:
42x + 12y = 129,360
-(21x + 12y = 129,480)
------------------------
21x = -120
x = -120/21
Substituting the value of x in equation (1), we get:
6(-120/21) + 4y = 18,480
-360 + 4y = 18,480
4y = 18,840
y = 4,710
Therefore, the price of 1 television is Rs. 4,710.
Method 2: Using substitution method
From equation (1), we can write:
6x = 18,480 - 4y
x = (18,480 - 4y)/6
Substituting this value of x in equation (2), we get:
14((18,480 - 4y)/6) + 2y = 18,480
Simplifying this equation, we get:
y = 3,360/2 = 1,680
Therefore, the price of 1 television is Rs. 1,680.
However, we need to check if this solution satisfies the first equation as well.
Substituting y = 1,680 in equation (1), we get:
6x + 4(1,680) = 18,480
6x = 11,040
x = 1,840
Therefore, the cost of 1 radio is Rs. 1,840.
Hence, the solution is:
- Price of 1 television = Rs. 1,680
- Price of 1 radio = Rs. 1,840
- Selling 6 radios + 4 televisions = Rs. 18,480
- Selling 14 radios + 2 televisions = Rs. 18,480
To find:
- Price of 1 television
Solution:
Let the cost of 1 radio be x and the cost of 1 television be y.
From the given information, we can form the following equations:
6x + 4y = 18,480 ...(1)
14x + 2y = 18,480 ...(2)
We need to find the value of y.
Method 1: Using elimination method
Multiplying equation (1) by 7 and subtracting it from equation (2) multiplied by 3, we get:
42x + 12y = 129,360
-(21x + 12y = 129,480)
------------------------
21x = -120
x = -120/21
Substituting the value of x in equation (1), we get:
6(-120/21) + 4y = 18,480
-360 + 4y = 18,480
4y = 18,840
y = 4,710
Therefore, the price of 1 television is Rs. 4,710.
Method 2: Using substitution method
From equation (1), we can write:
6x = 18,480 - 4y
x = (18,480 - 4y)/6
Substituting this value of x in equation (2), we get:
14((18,480 - 4y)/6) + 2y = 18,480
Simplifying this equation, we get:
y = 3,360/2 = 1,680
Therefore, the price of 1 television is Rs. 1,680.
However, we need to check if this solution satisfies the first equation as well.
Substituting y = 1,680 in equation (1), we get:
6x + 4(1,680) = 18,480
6x = 11,040
x = 1,840
Therefore, the cost of 1 radio is Rs. 1,840.
Hence, the solution is:
- Price of 1 television = Rs. 1,680
- Price of 1 radio = Rs. 1,840
