Suresh is now 19 years old and in college. Since he was a 5-year-old, he stayed in a hostel and is now coming back home after 14 long years. His parents have texted him the direction from the railway station to his house. See the below text message sent to Suresh by his parents and answer  the following question accordingly. “When you step out of the railway station, you are facing north. Take a right and drive 4 km, you will see a T-point/junction. Take a right and drive 2 km. There will be a roundabout with four roads. Take the second left from the round-about and drive 1 km. Take a right and drive 3 km. Take a left and drive 2 km. You will find our house at the front. Come home fast.” How many kilometers did Suresh drive after taking the second-left from the roundabout to reach his home by following the directions given by his parents?

After taking the second left from the roundabout, Suresh drives:  1 km straight,

then 3 km after turning right,

then 2 km after turning left.

So, total distance = 1 + 3 + 2 = 6 km.

Thus, correct option is (b).
