The value of land increases by a% during June and decreases by b% during July. If the value of the land is the same at the end of July as at the beginning of June, what is b in terms of a?	Choose the correct choice from the following answers: A) 200a/(100+2a) B) 100a/(100+a) C) a(2+a)/(1+a)2 D) a(200+a)/10000 E) 2a/a+2a
let the value of land be : x   it is increased by a%, new value= (x)+(ax/100)   now, it is decreased by b%, such that it equals the initial value   hence final value of land= x(1+a/100) - x(1+a/100)(b/100)= x(1+a/100)(1-b/100)=x   solving for b you get b=100a/(100+a)   ANSWER:100a/(100+a)
