Question:
The ages of two persons differ by 16 years. If 6 years ago, the elder one is 3 times as old as the younger one, find their present ages.
A ) 15 years and 31 years
B ) 14 years and 30 years
C ) 13 years and 29 years
D ) 12 years and 28 years
Answer: B)14 years and 30 years
Explanation:
Let the age of the younger person be x years.
Then, age of the elder person = (x + 16) years.
=> 3 (x – 6) = (x + 16 – 6)
=> 3x -18 = x + 10
=> 2x = 28
=> x = 14.
Hence, their present ages are 14 years and 30 years.
