Five friends are playing a game.Nitin is facing South.He follows instructions given by his friench him Nitin walks 50 metre. (i) When Kimi touch him Nitin turns right and walks 40 metre. (ii) When Neha touch him Nitin turns left and walks 40 metre. (iii) When Annut touch him Nitin walks 70 metre in the direction opposite to (which he faces. Grom his starting point? Gom his starting point? A.60 metre. B.quad Ta metre. B.quad Bo metre. D.75 metre. D.None of these

72.111

Nitin just needs to follow instructions in the given order:

1. Faces South
2. Walks straight 50m, now he still faces South
3. Turns right & walks 40m, now he faces West
4. Turns left & walks 80m, now he faces South
5. Walks 70m in opposite(North opposite to South) direction which means he is 10m(80m - 70m) away from the previous place

Now, to find out the difference in the distance between the starting & Ending point, we have 2 sides 40m & 60m(50+10).

As per the Pythagoras theorem,
R2 = X2 + Y2
R2 = (40*40) + (60*60) = 1600 + 3600 = 5200
R = 72.11 ~= 72m

72 how? Please explain

Sir,please do rewrite the question correctly along with options .By the way what is Grom and Gom?? is it from?
