Correct Answer

✅ Option c — 15\displaystyle 15

All Options:

  • A10\displaystyle 10
  • B20\displaystyle 20
  • C15\displaystyle 15
  • D25\displaystyle 25

Detailed Solution & Explanation

Starting at home (0,0)\displaystyle (0,0), Ram cycles 10 km South to (0,−10)\displaystyle (0, -10).
He then turns right (West) and travels 5 km to (−5,−10)\displaystyle (-5, -10).
He turns right again (North) and goes 10 km to (−5,0)\displaystyle (-5, 0).
Finally, he turns left (West) and travels 10 km to (−15,0)\displaystyle (-15, 0).
The straight-line distance from his final position (−15,0)\displaystyle (-15, 0) to home (0,0)\displaystyle (0,0) is:
Distance=5+10=15 km\text{Distance} = 5 + 10 = 15\text{ km}
Hence, **Option C** is the correct answer.
