Looking at the values / percentage, its clear that Company X costlier than Company Y
Just observed the OA; they have 4 distinct numbers after decimal point
Total calculation of company x gives .00 + .00 + .50 = .50 at the decimal
Total calculation of company y gives .00 + .90 + .00 = .90 at the decimal
There difference provides .60 at the decimal; only 41.60 fits in
Answer = A

Total charges of company A: 575+0.04*575+82.5=680.5;
Total charges of company B: 530+0.03*530+93=638.9;
If we deal with company B, which offers the lower price, we can save 680.5-638.9=41.6 dollars.
Answer: A.
