To calculate the final discount for each series, we apply each discount consecutively on the remaining price after the previous discount. For the 20/10/5 discount: 100 * (1 - 0.20) = 80, then 80 * (1 - 0.10) = 72, and finally 72 * (1 - 0.05) = 68.4, which means a total discount of 31.6%. For the 25/12/10 discount: 100 * (1 - 0.25) = 75, then 75 * (1 - 0.12) = 66, and finally 66 * (1 - 0.10) = 59.4, which means a total discount of 40.6%. Therefore, the 25/12/10 discount offers the best final discount.
