Question

the ratio of ages of father and son before 10 years was was 11:3. after 5years, the age of father will be years more than the twice the age of son. if both of them live, in how many years the son becomes as old as father is now​

Answer 1

Answer:

Let Son's age = S

Father's age = F

then, F−10=3(S−10)

F=3S−20

and, F+10=2(S+10)

F=2S+10

Thus, 3S−20=2S+10

S=30 years

Hence, F=70 years
