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 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
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
Six years ago Anita was P times as old as Ben was. If Anita is now 17 years old, how old is Ben now in terms of P ?
Let Ben’s age now be B
Anita’s age now is A.
(A - 6) = P(B - 6)
But A is 17 and therefore 11 = P(B - 6)
11/P = B-6
(11/P) + 6 = B
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
