For a certain car repair, the total charge consisted of a charge for parts, a charge for labor, and a 6 percent sales tax on both the charge for parts and the charge for labor. If the charge for parts, excluding sales tax, was $50.00, what was the total charge for the repair?
(1) The sales tax on the charge for labor was $9.60.
(2) The total sales tax was $12.60.

A. Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.
B. Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient.
C. BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient.
D. EACH statement ALONE is sufficient.
E. Statements (1) and (2) TOGETHER are NOT sufficient.

Correct option is (A)

Lets say total charge X = 1.06 ( Parts + Labour)
its given parts = 50
so x = 1.06 ( 50 + Labour)

S1: The sales tax on the charge for labor was $9.60

That means labour would been = 160
So S1 is sufficient.

S2: The total sales tax was $12.60.

This statement dosen't provide any information about the distribution of parts & labout in our original euation:
X = 1.06 ( Parts + Labour)

There are multiple answers for S2, so it is insufficient.

Hope that helps.

2) total salex tax 12.60
we know the tax rate 6% and parts cost $50

we can find parts tax $3 from there and subtract from 12.60 which gives 9.60
from 9.60 we can calculate the price 9.60*100/6 =160

therefore sufficient

D
both are suff
