The least number that must be substracted from 63520 to make the result a perfect square is
if a^2=by+cz, b^2=cz+ax, and c^2=ax+by, then value of x/(a+x) +y/(b+y)+z/(c+z) is
options 1 a+b+c 1/a+1/b+1/c 0
options 11, 83/9 7 13/9
a)4 b)8 c)1 d)2
@SujataPatil @caemento When the question comes asking for maximum possiblities and minimum possibilities and includes variables, concentrate on two things 1. boundary conditions 2. which variables has to be considered or varied (this part comes only with practise)....... When too many variables are there, use options rather than solving and check if it satisfies the boundary conditions......
@SujataPatil can u just repost that image which u had posted in morning.... I am on desktop now... Its better u upload it as a separate post.
