Question

Two years ago the ratio of the ages of Ramm and Gopal was 2:3, what is the present age of Gopal, if that of Ram is 20 years?​

Answer 1

Answer:

40years

Step-by-step explanation:

Let the present ages of Mohan and Gopal be x  and y respectively ,

∴yx=54⇒5x−4y=0⟶(i)×5

After 8 years , there ages will be (x+8) years and (y+8) years 

∴ According to question

y+8x+8=65⇒6x+48=5y+406x−5y=−8⟶(ii)×425x−20y=024x−20y=−32

On substracting : x=32 years

putting x in ⟶(i),

4y=5×32

∴y=40 years.
