The second is faced with 200 4096 byte frame per second. Which bridge do you think will need the faster CPU? I know that the answer is first case but why ? Acc to me the context switches and all depends on the number of frames passing through point which is higher in second case. So how is it that ans if first case ?

Although the other one has a higher throughput, the 100 frames/sec bridge has more interrupts, more process switches, more frames passed and more of everything that needs the CPU.
