2). There is a 1 km long wire placed on some no. of poles which r in equal distance. If the no of poles

is reduced by 1 then the distance of wire between each poles

increases 1 2/3.how many poles are there initially.

Ans: Let there r N poles before.

Then the distance betn two adjacent poles is =1000/(N-1)

After removing one pole distance betn two adjacent poles is= 1000/(N-2)

Now 1000/(N-1) + (5/3) = 1000/(N-2)

(N-1) * (N-2) =600

Solve it ans is 26
