Q. Two friends X and Y start running and they run together for 50 m in the same direction and reach a point. X turns right and runs 60 m, while Y turns left and runs 40 m. Then X turns left and runs 50 m and stops, while Y .turns right and runs 50 m and then stops. How far are the two friends from each other now?

Explanation : 

Two friends X and Y start running

After running together for 50 meters in the same direction and reaching a point, X turns right and runs 60 meters while Y turns left and runs 40 meters.

This means that they are now 100 meters apart from each other on a straight line (60 + 40 = 100).

Then X turns left and runs 50 meters and stops while Y turns right and runs 50 meters and then stops.

Since both X and Y ran in the same direction for the same distance (50 meters), their distance from each other remains unchanged at 100 meters.
