Aptitude Problems on Ages Test Paper 26) The sum of the ages of father and his son is 44 years. If 6 years after the father will be 3 times as old as his son, what are their present ages?
The Correct answer is (A) Explanation: Let present age of son is X and present age of father is (44 X). As per question, after 6 years; 3(X+6) = (44  X) +6 3X +18 = 50  X 4X = 50  18 4X = 32 X = 8 years ∴Present age of son = 8 years And, present of father = 44  8 = 36 years Solution 2; 7) Ten years ago, Ajay wasrd as old as Vijay. If Ajay is 18 years old now, how old is Vijay now?
The Correct answer is (B) Explanation: Let Vijay is X years old now. As per question, 10 years ago; (X10) = 18 ? 10 X 10 = 24 X = 24 +10 = 34 years 8) Age of father is seven times the age of his son. In the next 10 years, the age of father will be three times the age of his son. What is the age of father now?

If the ratio of their present ages is 4:3 respectively, find the difference between their present ages.
The Correct answer is (B) Explanation: Let 12 years ago age of Badri was X years and age of Budh was 2X. So, present age of Badri = X + 12 And, present age of Budh = 2X + 12 As per question; 6X + 36 = 4X + 48 2X = 12 X = 6 Present age of Badri = 6 + 12 = 18 years Present age of Budh = 2*6 +12= 24 years Required difference between their ages = 24  18 = 6 years 10) Two years ago the ratio of ages of Naresh and Suresh was 3:2. If one year hence, the ratio of their ages will be 7:5, what is the sum of their present ages?
