Question

Shrikant from a certain place went $4$ km to East. He turned left and went $1$ km. Then he turned right and went $2$ km. Again he turned right and walked a distance of $9$ km. Then at what distance is he from his original position ?

• A. $4$ km
• B. $10$ km
• C. $9$ km
• D. $6$ km

Answer 1

The correct option is B $10$ km

Srikant Travel 4Km East
From There he took Left and travel 1 km
Than he took Right and travel 2 km
Again he took Right and travel 9 km
Distance from original position = $\sqrt{(6{)}^2+(8{)}^2}$
$\sqrt{36+64}$ = $\sqrt{100}$ $=10$ km.
Hence, option 'B' is correct.
