guys just a small question..is sqrt of x there could be a case that x i have read somewhere that x sqaure underroot (sqrt) is always positive...pls let me know..

thanx manish and dabas.. however just wanted to know that sqrt (x2) is always positive..isint it? i think i read it some where..pls confirm it..that was the reason why i was getting 1 in this case. same is the case with the 1st question in the second doc 'gprep2'.. pls have a look at it as well..there are 3 questions which i did not get in that doc..thanx

Though these were posted before ..but no one was able to give the strategy properly..examples etc...would really appreciate if someone can help in explaining with examples.

few more...and 2 below: 1. If x 2. A wire 40 m long is cut into 2 pieces, one is used to form a circle with radius r and the other is used to form a square. No wire is left over. What is the total area of the circular and the square regions in terms of r? Pie r2 Pie r2+10 Pie r2+1/4 pie2 r2 Pie r2+(40-2pie r)2 Pie r2+(10-1/2pie r)2

few of these are very general..but i would like to know if someone can provide the solution with an example.,,i manage to solve these but m taking long...thanx

Did not understand the meaning?

even i would vote for c... the questions is quite confusing. As the argument states that there is a decline in the no. of assemblers and this would result to an increase in imports...then there could be a possibility of C...not sure
