The cost of 8 pens and 4 pencils is Rs. 176 and the cost of 2 pens and...
Given information:
Cost of 8 pens + 4 pencils = Rs. 176
Cost of 2 pens + 2 pencils = Rs. 48
To find: Cost of one pen
Let's assume the cost of one pen as 'x' and the cost of one pencil as 'y'.
Equations can be formed as follows:
8x + 4y = 176
2x + 2y = 48
Simplifying the second equation by dividing both sides by 2, we get:
x + y = 24
Now we have a system of two equations with two variables.
We can solve this system of equations using the method of substitution or elimination.
Using the method of elimination:
Multiply the second equation by 4 to make the coefficients of 'y' the same in both equations:
4(x + y) = 4(24)
4x + 4y = 96
Now subtract the first equation from the modified second equation:
(4x + 4y) - (8x + 4y) = 96 - 176
-4x = -80
Divide both sides by -4:
x = 20
Therefore, the cost of one pen is Rs. 20.
The correct answer is option 'E' (None of these).
Cost of 8 pens + 4 pencils = Rs. 176
Cost of 2 pens + 2 pencils = Rs. 48

Let's assume the cost of one pen as 'x' and the cost of one pencil as 'y'.
Equations can be formed as follows:
8x + 4y = 176
2x + 2y = 48
Simplifying the second equation by dividing both sides by 2, we get:

Now subtract the first equation from the modified second equation:
(4x + 4y) - (8x + 4y) = 96 - 176
-4x = -80
Divide both sides by -4:
x = 20
Therefore, the cost of one pen is Rs. 20.
The correct answer is option 'E' (None of these).
