The pair of linear equations 3x + 5y = 3, 6x + ky = 8 do not have any ...
For having no solution -->
a1/a2=b1/b2 is not equal to c1/c2,
or,3/6=5/k is not equal to3/8,
3/6=5/k,
k=10,
that's why option 'B' is correct

The pair of linear equations 3x + 5y = 3, 6x + ky = 8 do not have any ...
The coefficients of x and y in the two equations are proportional to each other.
In other words, if we can multiply one equation by a constant factor to obtain the other equation, then the system has no solution.
To check if this is the case for the given equations, we can compare their coefficients:
3x + 5y = 3
6x + ky = 8
If we multiply the first equation by 2, we get:
6x + 10y = 6
Comparing this to the second equation, we see that if k is equal to 10, then the two equations become equivalent.
Therefore, if k = 10, the pair of linear equations 3x - 5y = 3, 6x - 10y = 8 has no solution.
