It is important to do the
calculations very carefully. Otherwise there is nothing complicated about this
problem.
Let us assume the unknown number = x Then 40x/100 = 55 40x = 55 * 100 40x = 5500 x = 5500/40 = 550/4 = 137.5 So
55 is 40% of 137.50. I hope the procedure is clear to you and in future
you can solve such problems on your own without requiring any help from
outside.This is the simplest way of solving such
problems.
