Question

present ages of p and q is 3:4. four years hence q will be 5 years older than p what is p present age

Answer 1

Let the present age be 3x and 4x


Then,

(4x + 4) - ( 3x + 4) = 5

4x - 3x = 5

x = 5


P's present age = 3x = 3 × 5 = 15 years.

Answer 2

Let p's age be 3x years and q's age be 4x years
A/Q
$4x + 4 = (3x + 4) + 5 \\ = > 4x + 4 = 3x + 9 \\ = > x = 5$
Therefore,
P's age =3 x 5
=15 years
Q's age=4 x 5
=20 years
