Problema Solution
a man is thrice as old as his son.After 10 year the sum of their ages will be 84. find their present ages?
Answer provided by our tutors
Let 2x = Man's age now.
Let x = Son's age now.
In 10 Years
2(x + 10) = Man's age in 10 years
x+10 = son's age in 10 years
2(x+10)+x+10 = 84 ===> 3x = 54 ==> x = 18
hence, man's age in 10 years is 28 years, a man's age is 56 years
