A father said his son , " I was as old as you are at present at the time of your birth. " If the father age is 38 now, the son age 5 years back was :
Let the son's present age be x years .Then, (38 - x) = x x= 19.
Son's age 5 years back = (19 - 5) = 14 years
The total age of A and B is 12 years more than the total age of B and C. C is how many years younger than A ?
(A+B) - (B+C) = 12
A - C = 12.
C is younger than A by 12 years.
A person's present age is two-fifth of the age of his mother. After 8 years, he will be one-half of the age of his mother. How old is the mother at present
Let the mother's present age be x years. Then, the person's present age = years.
2(2x + 40) = 5(x + 8)
x = 40
Five years ago, the average age of A, B, C and D was 45 years. With E Joining them now, the average of all the five is 49 years. The age of E is?
5 years ago average age of A,B,C,D = 45 years
5 years ago total age of A, B, C, D = 45 x 4 = 180 years
Total present age of A, B, C, D = 180 + 5x4 = 200 years
If E's present age is x years
In 10 years, A will be twice as old as B was 10 years ago. If A is now 9 years older than B, the present age of B is :
Let B's present age = x years. Then, A's present age = (x + 9) years.(x + 9) + 10 = 2(x - 10)
=> x + 19 = 2x - 20
=> x =39.
