How many characters per second can be transmitted over a 1200-band line in each what modes considering a character code of 8 bits synchronous serial transmission asynchronous with 1 stop?

for 8 bit synchronous serial transmission total transmitted characters will be

1200/8

and for asynchronous transmission with 1 stop total bit will be (8+1+1=10) i.e. (8 bit + start bit+stop bit)

so transmitted characters will be

1200/10
