Q1:

A farmer built a fence around his square plot. He used 27 fence poles on each side of the square. How many poles did he need altogether ?

A 100

B 104

C 108

D None of these

ANS:B - 104

Explanation: Since each pole at the corner of the plot is common to its two sides, so we have : Total number of poles needed = 27 x 4 - 4 = 108 - 4 = 104.
