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?
Read Solution (Total 1)
-
- Let the present age of P and Q be 3x and 4x respectively.
Ten years ago, P was half of Q in age
=> (3x – 10) = ½ (4x – 10)
=> 6x – 20 = 4x – 10
=> 2x = 10
=> x = 5
total of their present ages = 3x + 4x = 7x = 7 × 5 = 35 - 10 years agoHelpfull: Yes(1) No(0)
