Marks: +1, -0

Walking at 4 km an hour, a peon reaches his office 5 minutes late. If he walks at 5 km an hour, he will be 4 minutes too early. The distance of his office from the residence is—

5 km
4 km
3 km
2 km

Validate

Solution:

Let distance be x km.
Then,

{ x } /{ 4 } - { x } /{ 5 } = { 9 } /{ 60 }

⇒

{ 5 x - 4 x } /{ 20 } = { 9 }/ { 60 }

⇒ 5x – 4x =

{9×20}/60

⇒ x = 3 km
