Puys please help me with this question :

A city has a circular wall surrounding it. The wall has 4 gates located at the east, west, north and south points. A temple stands at a distance of 1 km to the east of the east gate outside the city. It can be seen by a person standing sqrt(3) km directly to the north of the west gate, but if any closer to the west gate, the wall obstructs his view of the temple. Find the radius of the wall which surrounds the city (in km).

A)1 B)2 C)3 D)4.

I tried solving it, but couldn't find the answer in the options..

There are 7 children standing in a line,not all oh whom have same no of cakes with them.If the first child distributes his cakes to the remaining 6 children,such that he doubles their resp no.of cakes,then he will be left with 4 cakes.Instead if 2nd child takes away 2 cakes from each of the remaining 6 children,then he will be left with 3 cakes less than the no of cakes that the 1st child initially had.What is the total no of cakes that are there with 3rd to 7th child???

> 2) for y=5, x^3-4x^2 = 100^2*96 only one power of 3 so the highest term must have only one power of 3. and the minimum power of 2 is 3 for y=3....so it should be 24 Didnt understad this part..could u pls elaborate..
