Answer:
she not done homework
Explanation:
Step-by-step explanation:
Let the present ages be :
Liya = x
Raja = 2x
Ages 5 years ago :
Liya = (x - 5)
Raja = (2x - 5)
According to the Question,
Five years ago Raja's age was three times Liya's age
\sf{\longrightarrow} \: (2x - 5) = 3(x - 5)⟶(2x−5)=3(x−5)
\sf{\longrightarrow} \:2x - 5 = 3x - 15⟶2x−5=3x−15
\sf{\longrightarrow} \:2x - 3x = - 15 + 5⟶2x−3x=−15+5
\sf{\longrightarrow} \:x = 10⟶x=10
Liya's present age = 10 years
___________________
★ Raja's present age =
\sf{\longrightarrow} \:2(10)⟶2(10)
\sf{\longrightarrow} \:20⟶20
Raja's present age = 20 years
Therefore, Raja and Liya are 20 and 10 years old respectively.
