Comprehension: (Que No. 1-3 Direction: Read the instruction carefully and answer the question given below. A person starts from point L and goes 5 km towards the east to reach point M and then takes a left turn and travels 2 km to reach point N. Upon reaching point N he turns right and goes 3 km to reach point O and then turns right again and goes 6 km to reach point P. From point P he takes a left turn and goes 3 km to reach point Q and then again turns left and goes 4 km to reach point R. After reaching point R, he finally takes a left turn and goes 3 km to reach point S which is his destination. Question: What is the shortest distance between the starting and the finishing point? 10 km 12 km 6 km 5 km 8 km

To find the shortest distance between the starting point (L) and the finishing point (S), we need to consider the path taken by the person.<br /><br />Let's break down the path:<br /><br />1. From point L to point M: 5 km towards the east.<br />2. From point M to point N: 2 km to the left (assuming a left turn means a 90-degree left turn).<br />3. From point N to point O: 3 km to the right.<br />4. From point O to point P: 6 km to the right.<br />5. From point P to point Q: 3 km to the left.<br />6. From point Q to point R: 4 km to the left.<br />7. From point R to point S: 3 km to the left.<br /><br />Now, let's calculate the distance between the starting point (L) and the finishing point (S):<br /><br />- From point L to point M: 5 km.<br />- From point M to point N: 2 km.<br />- From point N to point O: 3 km.<br />- From point O to point P: 6 km.<br />- From point P to point Q: 3 km.<br />- From point Q to point R: 4 km.<br />- From point R to point S: 3 km.<br /><br />Adding up all the distances, we get:<br /><br />5 km + 2 km + 3 km + 6 km + 3 km + 4 km + 3 km = 26 km.<br /><br />Therefore, the shortest distance between the starting point (L) and the finishing point (S) is 26 km.
