Question 23
Herman is a busy baker who must make raisin bread and pandan bread for his customer. He has one mixing bowl and one oven that holds only one type of bread at a time. He can prepare only one dough at a time, but while one bread bakes unattended he can prepare the other dough. Raisin bread needs 20 minutes to prepare and 27 to bake. Pandan bread needs 29 minutes to prepare and 23 to bake. What is the least total time, in minutes, to finish both?
Assume each preparation and baking stage runs without interruption, and moving dough into or out of the oven takes no extra time.
Answer format: enter one whole number without units. Leading zeros are optional; the source paper answer sheet uses four digits.
