There are a red paper tape and a white paper tape.
Red tape is cut to every 8 cm and white tape is cut to every 9 cm.
When I connected cut tapes by piling every 1 cm of the end of the cut tape with paste by turns so as to be different colors, it was 159 cm long.
Find the number of used sheets of red and white and the number of joint, respectively.
