Directions: Study the following questions carefully and answer the questions given below. Kunal walks 10 km towards North. From there he walks 6 km towards South. Then, he walks 3 km towards East. How far and in which direction is he with reference to his starting point?

Step-by-step solution

Clearly, Kunal moves from A 10 km north-wards up to B, then moves 6 km southwards up to C, turns towards East and walks 3 km up to D. Then, AC = (AB - BC) = (10 – 6) = 4 km. So, Kunal’s distance from the starting point A. AD = (AC 2 + CD 2 ) = 4 2 + 3 2 = 5 km. Also, D is to the North-east of A. Hence, option D is correct.
