Question

the ratio between the present ages of p and q is 3:4 respectively if q's present age is 20years what will be ration of the ages after 5years full solution

Answer 1

Solution :
p : q = 3 : 4

given,
q = 20 = 4x
so 4x = 20
x = 5

so P's present age = 3*5 = 15
after 5 years
p : q = (15+5) : (20+5) = 20 : 25

so p : q = 4 : 5

Answer 2

let the present ages of p and q be 3x and 4x years respectively.

q's age = 20 yrs.
4x = 20
x= 5

p's present age = 3x = 15 yrs.
Five years later, their ages,
q's age = 20+5 = 25 yrs.
p's age = 15+5 = 20 yrs.

Ratio of ages of p and q after 5 years=
20:25 = 4:5 ans.
