Given : Jacob is 2 times as old as Mark.
16 years later, Jacob will be 2 more than 4 times Mark’s present age.
To Find : Jacob’s and Mark’s present ages.
Solution:
Let say mark present age = M years
Jacob is 2 times as old as Mark
Hence Jacob present age = 2M years
16 years later, Jacob will be 2 more than 4 times Mark’s present age.
=> 2M + 16 = 4M + 2
=> 2M = 14
=> M = 7
Hence mark present age = 7 years
Jacob present age = 14 years
