A. $41.60
B. $45.00
C. $50.75
D. $55.75
E. $61.25

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

The table above shows the various charges made by two companies for the same air conditioner. What is the total amount that can be saved on the purchase and installation of the air conditioner by dealing with the company that offers the lower total charge?

A. $41.60
B. $45.00
C. $50.75
D. $55.75
E. $61.25

What is being asked in this question?


Approximate the difference:

X - Price 45 extra
X - 4% of 575 is 4 times 1% of 575 which is 4 times 5.75, which is 23.
Y - 3% of 530 is 3 times 1% of 530 which is 3 times 5.3 say about 16.
So Surcharge of X is about 7 extra.

Y - Installation costs about 10 extra.

So overall, X costs about 42 extra.

Answer (A)
