When you were 14 years old your father was 42 years old which was three times your age now he is twice your age how old are you?
"When you were 14 years old, your father was 42 years old". - that gives us the difference in age. The father is 42 - 14, or 28 years older than the child. "which was three times your age" - that's a decoy. It's true, 14 times three is equal to 42, but it doesn't tell us anything we don't already know. "now he is twice your age, how old are you?" - this is the other piece of information we need. Combining this with the first statement will let us find the answer: Let the father's age be "F", and the child's age be "C". We can then say that, given the first statement: F = C + 28 because that statement told us that the father is twenty-eight years older than the child. We can also say: F = 2C as that's what the last statement tells us. Now all we need to do is combine those two statements: F = C + 28 ∴ 2C = C + 28 ∴ C = 28 So the child is now 28 years old. You can also find the father's age by plugging it into one of the previous equations. We know that F = 2C, so the father's age is 2 * 28, which equals 56.
