Meena walks 14 metres towards west, then turns to her right and walks 14 metres and then turns to her left and walks 10 metres. Again turning to her left, she walks 14 metres. What is the shortest distance between her starting point and the present position?

A) 10

B) 24

C) 28

D) 38

E) None of these

Correct Answer: B

Solution :

Explanation Option (b) is correct. The movement of Meena is as shown in figure [A to B, B to C, C to D and D to E]. Clearly, Meena's distance from initial position \[\to AE=\left( AB+BE \right)\] \[\to AE=(AB+CD)\] \[\to AE=(14+10)m\] \[\to AE=24m.\]
