Hi Simmi Sharma!! It's simple if you are perfect in series and parallel combination.
See, you need to find out how many capacitors/condensers are needed to make effective of (20uf,440uf). You need to increase the voltage rating 2 times in series(voltage varies in series combinatin). So, 1/c= 1/20+1/20 > C=10uf
In series combination it is (10uf,440V).
To have capacitance of 40uf you should connect 4 such in parallel combination (Ceff. =Sum of each capacitance)
So, no.of capacitors=n×m
= 2 nos.for each series combination× 8such parallel combination. = 16 capacitors:-):-):-)
