Q11) The age of a man is equal to the sum of the ages of his son and daughter. The ratio of the age of the son to that of the daughter is 5 : 4. If the age of the man is 45 years, find the ages of his son and daughter.

Step-by-step explanation:

Let the ages of son and daughter be 5x and 4x Then

By the question

The age of a man is equal to the sum of the ages of his son and daughter . So

5x + 4x = 9x

Now

it is given that

age of the man = 45

or 9x = 45

x = 45 / 9

x = 5

Finally

Age of son = 5x = 5 * 5 = 25

Age of daughter = 4x = 4 * 5 = 20

Hope it will help :)❤
