Right in the topic, it is very clear that the difference between the sum of the ages of 4 brothers and the age of the mother, requires finding the number of years for the two data to be equal. In this problem, it is only necessary to apply the calculations learned in elementary school to perform, but there are still many people and Olympia contestant giving wrong answers.
The answer to this question is: 5 years.
We have, after each year, the sum of the ages of the 4 brothers will increase by 4, the age of the mother will increase by 1, the difference between these two facts is 3. So to shorten the 15 year gap, divide by 15 3 will give an answer of 5 (five).
Although the numbers are not large and quite simple, if calculating in a short time, many people may be confused a bit. Therefore, besides agility, it also needs meticulousness and absolute accuracy to solve these puzzles. Are you confident to be an Olympia contestant after answering this question?
