A’s age is the sixth part of his father’s age. After 10 years, the age of A’s father will be twice the age of B. If B’s 4th birthday is celebrated 3 years ago, then what is the current age of A?
Let A’s age be x years and father’s age be 6x years. Present age of B = 4 + 3 = 7 years After 10 years, => 6x + 10 = 2(7 + 10) => 6x = 34 – 10 => x = 24/6 = 4 years
