parallel is the connection where u have the resistors being connected together at two common points. as such, they are both maintained at the same voltage, while the current flowing through them depends on their resistances.
for 2 resistances R and r in parallel, net resistance = rR/(r + R).
IN series, the resistors are connected to the same current supply, such that htey all have different voltages appied.here net resistance = r + R.
MIXED RESISTANCE IS ONE WHICH CONTAINS RESISTORS IN SERIES AS WELL AS IN PARALLEL.

There are two basic ways of connecting two resistors (or any other two terminals devices for that matter). A series combination, in which the same current flows through each one, and a parallel combination, in which they share the same voltage. I assume that what you mean by a mixed combination is a combination of any number of any number of the above basic combinations. The equivalent resistance of two resistors or more in series is simply the sum of their resistances. The equivalent resistance of two or more resistors in parallel is the inverse of the sum of the inverses of their resistances. When ou consider three resistors, there are other combinations such as the Y (or star) and Delta combinations. If you are interested, let me know and I can explain further.

By mixed combination and parallel combination of resistance do you mean series and parallel resistance? If so, with series current is the same and voltage drop varies with resistance as determined by v = i x r. With parallel, voltage drop remains the same and current varies through each resistor by
i = v/r.

The term Mixed Combination of resistance means nothing to me without further explanation. Is this out of context here?
A mixed combination of parallel resistances would be OK.
A mixed combination of series resistances would be OK.
A mixed combination of series and parallel resistances would be OK.
OK?

mixed combination of resistors means dat d resistences are arranged in parallel n series as well.
and parallel means they r arranged parallel to each odr.
A SIMPLE WAY TO IDENTIFY IS :
in parallel the +ve of a resistance is connected to +ve and in series it is +ve to -ve.

mixed combination means some resistorsare comnnected inseries and some in parallel
parallel combination means all the resistors are connected in parallel
