The ratio between the present ages of P and Q is 3:4 .Four years hence Q will be five years older than P. What is P’s present age?

• Ratio of Present age => P : Q = 3:4
  Present age of (P : Q) ll be (3x : 4x)
  P = 3x
  Q = 4x
  
  4 years after, age of P, Q ll be
  (Q+4) = (P+4)+5
  Q = P+5
  4x = 3x + 5
  x = 5
  Present age of (P:Q) is (3x:4x) => 15:20
  P = 15 years
  Q = 20 years
  
  Ans : 15 years

• Let P's present age be 3x and Q's present age be 4x.
  After 4 years =>(4x+4) - (3x+4) = 5
  x=5
  So, P's present age = 3*5=15

• Let age of P be 3 x
  Then Q age 4x
  4 years hence means four years later
  P age= 3x+4
  Q age=4x+4
  Given, Q =P+5, after 4 years, t
  Thus
  4x+4=3x+4+5
  Thus x=5
  Thus P's present age 3*5=15

• 15let ps age bexthen qs age be x5xx534x15
• 10 years agoHelpfull: Yes(0) No(1)
• x/x+5=3/4
  x=5
  present ages are in the ratio 3x:5x.
  then p age is 3x=3*5=15
