Stanley starts cycling from Point A. He cycles X km towards the west and then turns right and cycles 3 km. He again turns right and cycles for X+1 km. He again turns right and cycles for 2X+1 km. He takes a final right turn and cycles for 1 km to stop at Point B. Point B is 6 km south of Point A. What is the value of X?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 4
RS = RT + TS
2x + 1 = PQ + AB
2x + 1 = 3 + 6
2x + 1 = 9
x = 4
From the figure, the value of x = 4
