A child went 90 m in the East to look for his father, then he turned right and went 20 m. After this he turned right and after going 30 m he reached to his uncle's house. His father was not there. From there he went 100 m to his north and met his father. How far did he meet his father from the starting point?

To find out the hypotenuse you could follow the 3:4:5 ratio instead doing the Pythagoras formula.

As we found the ratio of other two legs that is 80:60 which is 4:3, so we can assume that the ratio of other two legs and hypotenuse will be: 3:4:5, hypotenuse being the largest one. So, now just multiply 20 with the ratio number regarding hypotenuse. It is 100 (20*5).

Hope all understand.

If the child was facing the west then, what will be the meaning of "his north" doesn't it mean that he went straight considering the fact that the north is always in front. Please explain.

Yes @Rajat absolutely.

"His north" means he went straight.

Could be misleading, but then we have to look in the given options to what the question is really asking for.

Well here "his North" actually means the North direction according to the assumed East direction initially in the question. The word "from there" is just misleading.

Yes, absolutely Right @Gsg.

How far means, they are asking distance, not displacement.

So the solution is 240m.

They are asking how far he met is father not that how far his father is there from the starting point, so its total distance traversed i.e. 240m.
