a man is 4 years older than his wife. the wife is three times as old as their daughter.the present age of daughter is 10 years .how old was the man when his daughter was born?
w = 3d
d = 10
so wife = 30
Man is 4 years older = 34
His daughter was born 10 years ago so he must have been 24.
To find out how old the man was when his daughter was born, we need to determine the age difference between the man and his daughter.
Let's first determine the current age of the wife. We know that the wife is three times as old as their daughter, and the daughter is currently 10 years old. Therefore, the wife's current age is 3 * 10 = 30 years.
Since the man is 4 years older than his wife, his current age would be 30 + 4 = 34 years.
To calculate the age difference between the man and his daughter, we need to subtract the daughter's age from the man's age. The daughter is currently 10 years old, so the age difference is 34 - 10 = 24 years.
Therefore, the man was 24 years old when his daughter was born.
