The sum of the ages of Mr Lee and his son is 53 now. 4 years ago, the age of Mr Lee was 4 times that of his son. Find their ages
zepelin [54]

Answer:

Now, Mr Lee's age is 40 years, his son's age is 13 years.

Step-by-step explanation:

<u>4 years ago:</u>

Son's age = x years

Mr. Lee age = 4x years

<u>Now:</u>

Son's age = x + 4 years

Mr. Lee age = 4x + 4 years

The sum of the ages of Mr Lee and his son is 53 now, so

x+4+4x+4=53\\ \\x+4x=53-4-4\\ \\5x=53-8\\ \\5x=45\\ \\x=9\\ \\4x=36\\ \\x+4=9+4=13\\ \\4x+4=36+4=40

Now, Mr Lee's age is 40 years, his son's age is 13 years.
