A man drives 40 kms to the North and then, turning East, drives 50 kms. Again, he turns to his right and drives 30 kms. Once again, he turns to his right and drives 50 kms. How far is he from his starting place?

Correct option is D

Ans. (d)
Sol.
Let’s break the movement step by step:
Step 1: 40 km North
Step 2: 50 km East
Step 3: 30 km South (right turn from East)
Step 4: 50 km West (right turn from South)
Now, observe the final position:
Net North-South distance = 40 km (North) - 30 km (South) = 10 km North
Net East-West distance = 50 km (East) - 50 km (West) = 0 km
So, the person is 10 km to the North of the starting point.
Final distance from starting point = 10 km
