Question: Adam and Tom are brothers. Adam is 8 years old and Tom is 12 years old. In how many years will their combined age be 44 years old? Think carefully first, then make a decision:
At present, the two brothers have a combined age of 8 + 12 = 20 years old. Therefore, 1 year means an increase in the sum of their ages by 1 * 2 = 2 years. Adam and Tom need a total of 44 - 20 = 24 more years to be 44 years old together. So both brothers will be 44 years old together after 24 / 2 = 12 years. So the answer is 12.
