Ten years ago, P was half of Q in age. If the ratio of their present ages is 3:4, what will be the total of their present ages
Answer/Solution
5
Steps/Work
Let the present age of P and Q be 3x and 4x respectively.
Ten years ago, P was half of Q in age
=> 2(3x – 10) = (4x – 10)
=> 6x – 20 = 4x – 10
=> 2x = 10
=> x = 5
