SOLUTION

Stores Land M each sell a certain product at a different regular price. If both stores discount their regular price of the product, is the discount price at Store M less than the discount price at Store L ?

(1) At Store L the discount price is 10 percent less than the regular price; at Store M the discount price is 15 percent less than the regular price.
(2) At Store L the discount price is $5 less than the regular store price; at Store M the discount price is$6 less than the regular price.

Each statement is clearly insufficient to answer the question.

When we consider the statements together we have that 10% of regular price at store L corresponds to $5 and 15% of regular price at store M corresponds to$6. We can find regular prices, and discounted prices, thus answer the question. Sufficient.

Let the regular price at store L is 100L & at store M is 100M
1) Discounted price at L = 90L
Discounted price at store M = 85M
But still we don't the respective value of L & M --->Insufficient

2) Discounted price at L = 100L - 5
Discounted price at M = 100M - 6
But still we don't the respective value of L & M --->Insufficient

1+2) 10L = 5 & 15M = 6
We can get the respective value of L & M --->Sufficient

1) If Store L's cost is 10000000000000$and store M's cost is 10$, after the discounts Store L would be more expensive. If the case is vice versa, store M would be more expensive.

2) Again, If Store L's cost is 10000000000000$and store M's cost is 10$, after the deductions Store L would be more expensive. If the case is vice versa, store M would be more expensive.

Both statements together.
A 10% discount = 5$in store L. A 15 % discount = 6$ in store M.
So the prices before discount and the discounted prices for both stores can be found.

discount at store M < discount at store L ?

statement 1

L-0.10L=0.90L
M-0.15M=0.85M

statement 2

L-5
M-6 again insufficient

combining both

L-5=0.90L
M-6=0.85 M 2 equations 2 unknowns sufficient

0.15M = 6 >>> M=6/.15 = 40 therefore 40-6 = 34

0.1L = 5 >>> L=5/.1 = 50 therefore 50-5 = 45

34<45

Statment 1 gives us the % difference between regular and discounted prices for each store. But clearly not sufficient information to find out difference in discounted prices.

Statment 2 gives us the absolute difference between regular and discounted prices for each store. But clearly not sufficient information to find out difference in discounted prices.

However combining statement 1 and 2,we know that 10% corresponds to $5 for store 1 and 15% corresponds to$6 for store 2. With this we can find out regular price and therefore the discounted prices for each. Hence sufficient.

Stores Land M each sell a certain product at a different regular price. If both stores discount their regular price of the product, is the discount price at Store M less than the discount price at Store L ?

(1) At Store L the discount price is 10 percent less than the regular price; at Store M the discount price is 15 percent less than the regular price.
(2) At Store L the discount price is $5 less than the regular store price; at Store M the discount price is$6 less than the regular price.

We are given that stores L and M sell a certain product at different regular prices. We are also given that both of these stores discount the regular price of the product. We must determine whether the discount price at Store M is less than the discount price at Store L.

Statement One Alone:

At store L the discount price is 10 percent less than the regular price; at store M the discount price is 15 percent less than the regular price.

Even though we know the percent discount at each store, without actually knowing the regular price of the product at each store, we can’t determine the discount price of the product in each store. Thus, we can’t compare their discount prices. Statement one alone is not sufficient to answer the question. We can eliminate answer choices A and D.

Statement Two Alone:

At store L the discount price is $5 less than the regular store price; at store M the discount price is$6 less than the regular price.

Even though we know the amount of discount at each store, without actually knowing the regular price of the product at each store, we still can’t determine the discount price of the product in each store. Thus, we can’t compare their discount prices. We can eliminate answer choice B.

Statements One and Two Together:

From statements one and two we have the following information:

a) At store L the percent discount is 10% and the amount of discount is $5. b) At store M the percent discount is 15% and the amount of discount is$6.

Now if we let p = the regular price of the product at store L and q = the regular price of the product at store M. Then:

a) 0.10p = 5

b) 0.15q = 6

Thus p = 5/.10 = $50 and q = 6/.15 =$40. Furthermore, the discount price of the product at store L is 50 – 5 = $45 and the discount price of the same product at store M is 40 – 6 =$34. Thus, we know that the discount price at store M is indeed less than the discount price at store L.
