Question

Sol. (2) Let the age of Ram and Rahim 10 years ago be ( x ) and ( 3 x ) years respectively. After 5 years from now,
[
frac{x+15}{3 x+15}=frac{2}{3}
]
( Rightarrow 6 x+30=3 x+45 )
( Rightarrow 3 x=45-30=15 )
( Rightarrow quad x=5 )
( therefore ) Ratio of their present age ( =(x+10):(3 x+10) )
( =15: 25=3: 5 )

# Ex. 1. The ratio of the ages of Ram and ago was 1:3. The ratio of their age five years hence will be 2:3. Then the ratio of their present age is SSC CGL (Tier-I) 2014 (1) 1:2 (2) 3:5 (3) 3:4 (4) 2:5
