Directions: Study the following questions carefully and answer the questions given below. One day Ravi left home and cycled 10 km southwards, turned right and cycled 5 km and turned right and cycled 10 km and turned left and cycled 10 km. how many kilometers will he have to cycle to reach his home straight ?

Step-by-step solution

Clearly, Ravi starts from home at A, moves 10 km south wards up to B, turns right and moves and 5 km up to C, turns right again and moves 10 km up to D and finally turns left and moves 10 km up to E. Thus his distance from initial position A = AE + DE = BC + DE = (5 + 10) km = 15 km Hence, option B is correct.
