Question

Ek pita ki aayu apne putr ki aayu ki 4 guni hai 5 wars baad pita ki aayu apne putr ki aayu ki 3 guni ho jayegi tab pita wa putr ki wartman aayu hai

Answer 1

let the age of son be = x
thn age of father = 4x
After five years,
age of son = x+5
age of father = 4x+5
Given,
4x+5=3(x+5)
4x+5=3x+15
4x-3x=15-5
x=10
therefore present age of son = x = 10years
present age of father = 4x =4(10) = 40 years
