When Ajit travelled 15km, he found that one-fourth of his journey was still left.What was the full length of the journey?
Let the total length of journey=x
Journey travelled=15km
Journey still left=14 of x
Now, according to question,
x−15=14 of x
⇒x−15=x4
⇒x−x4=15
⇒4x−x4=15
⇒3x=60
∴x=603=20km
∴Total length of the journey=20km.
