Answer the questions based on the following information.
In a motor race competition certain rules are given for the participants to follow. To control direction and speed of the motorists, guards are placed at different signal points with caps of different colour. Guard with red cap indicates the direction of participant’s movement and guards with green cap indicates speed of the participant’s movement. At any signal point presence of three guards, two guards and one guard with red cap means the participants must stop, turn left and turn right respectively. Signal points with three guards, two guards and one guard with green cap means the participants must move at 10, 4 and 2 km/hour respectively.
Kartikay, one of the participants, starts at a point where his car was heading towards north and he encountered signals as follows: at starting point one guard with green cap; after half an hour two guards with red cap and two guards with green cap at first signal; after fifteen minutes one guard with red cap at second signal; after 24 minutes two guard with red cap and two guards with green cap at fourth signal; after 15 minutes three guards with red cap at fifth signal. (Time mentioned in each case is applicable after crossing the previous signal).
Q. No. 1:
Total distance traveled by Kartikay from starting point till last signal is:
Answer: A Note: s = Distance covered; v = Velocity (km/hr) t = Time taken; s = v × t The total distance travelled by the motorist from the starting point till last signal is 1 + 1 + 2 + 4 + 1 = 9 km
Q. No. 2:
What would be the final position of Kartikay if one guard with red cap and two guards with green caps were placed at the first signal point after the starting point?

Finally he turned right and drove 10km and then turned left to travel 19km. How far and in which direction is he from the starting point ?
Answer: C Hence required distance = (122 +52 )1/2 = 13 km.
Q. No. 6:
Arun started walking positioning his back towards the sun. After some time, he turned left, then turned right and then towards the left again. In which direction is he going now? I. North II. West III. South IV. East
Answer: B Aruns back was positioned towards the sun. Thus, depending on the time of the day, Arun could have been walking towards the West(morning) or towards the East(evening). Case I : Arun was walking towards the West. Thus, he finally faces the south. Case II : Arun was walking towards the East. Thus, he finally faces the north.
Hence, Arun could have been going either towards the South or towards the North.
