If price of guitar is P, and sales tax on it is S. Total price including sales tax = P + S = $624. We have to answer whether S > 3% of P or whether S > 0.03P
Statement 1. Lets say if P = $602, then with 3% sales tax, total price = 602 + 0.03*602 = 618.06, which is < 624 So that means even at price of 602, we need to apply sales tax of greater than 3% so as to reach the required amount of 624. Thus when the price is less than 602, definitely for every such case sales tax would need to be higher than 3% to reach the required amount of 624. Thus sufficient.
Statement 2. Sales tax is < $30. Sales tax could be $4, thus P = $620, here tax is < 3% But sales tax could be $24, thus P = $600, here tax is > 3% Clearly the statement is not sufficient.
Hence A answer

Max purchased a guitar for a total of $624,which consisted of the price of the guitar and the sales tax.Was the sales tax rate greater than 3 percent ?
(1) The price of the guitar that Max purchased was less than $602.
(2) The sales tax for the guitar that Max purchased was less than $30.
Solution:
Tricky one. Be aware of the trap.
Statement 1: First calculate what's 3% of 624. It is 3x6.24=18.72. The difference between C.P of guitar and Cost paid is 624602=22. Therefore it is clear that the sales tax rate is greater than 3%.
Statement 2: We don't know the exact value of the sales tax. Though it is lesser than 30, it can be lesser,equal or greater than 3%(18.72). Insufficient.
Therefore, the answer is Option A.

(1) The price of the guitar that Max purchased was less than $602.
(2) The sales tax for the guitar that Max purchased was less than $30. (1) The price of the guitar that Max purchased was less than $602.
Maximum price of guitar can be 601. therefore sales tax price would be \(624  601 = 23\)
Minimum sales tax percent \(= \frac{23}{624}*100 = 3.6\)%.
Any reduction in the price of guitar will increase the sales tax price, ie; numerator will increase and hence the sales tax percent will also increase. Therefore sales tax rate is greater than 3%.  I is Sufficient.
(2) The sales tax for the guitar that Max purchased was less than $30.
Maximum sales price would be $29 (less than $30). Therefore Sales price rate \(= \frac{29}{624} * 100 = 4.6\)%
or
If sales price is $1. Sales price rate \(= \frac{1}{624} * 100 = 0.16\)%
(2) gives multiple values of sales price rate. II is Not Sufficient.
Only I alone is Sufficient. Answer (A)

(1) The price of the guitar that Max purchased was less than $602.
(2) The sales tax for the guitar that Max purchased was less than $30. We are given that Max purchased a guitar for a total of $624, which was the price of the guitar and the sales tax. If we let the price of the guitar = p and n = the tax rate, then we have: 624 = p + (n/100)p 624 = p(1 + n/100) 624 = p[(100 + n)/100] 62,400 = p[(100 + n) 62,400/(100 + n) = p We need to determine whether n > 3. Statement One Alone: The price of the guitar that Max purchased was less than $602. Since p < 602 and 62,400/(100 + n) = p, we have: 62,400/(100 + n) < 602 62,400 < 60,200 + 602n 2,200 < 602n 2,200/602 ≈ 3.65 < n Since n is greater than 3.65, the sales tax is greater than 3%. Statement Two Alone: The sales tax for the guitar that Max purchased was less than $30. Statement two alone is not sufficient to answer the question. For instance, if the tax was $0, then the tax rate was less than 3%; however, if the tax was $24, the price of the guitar would be $600, and the tax rate would be 24/600 = 4/100 = 4%, which is greater than 3%. Answer: A

Only I alone is Sufficient. Answer (A)Though Answer is A, the sale tax is calculated on the price of guitar ie. 601 or less. It cant be calculated in total. Total = Price + sale tax. Am I wrong ?

(1) The price of the guitar that Max purchased was less than $602.
(2) The sales tax for the guitar that Max purchased was less than $30. Target question: Was the sales tax rate greater than 3 percent? Given: Max purchased a guitar for a total of $624, which consisted of the price of the guitar and the sales tax. Statement 1: The price of the guitar that Max purchased was less than $602. Let's see what would happen if the sales tax were EXACTLY 3% 1% of $602 = $6.02 So, 3% of $602 ≈ $18 So with a sales tax of EXACTLY 3%, the tax would be $18 This means the TOTAL price would equal $602 + $18 = $620 However, we're told that Max paid $624. Therefore, the tax rate must be GREATER than 3% NOTE: we're actually told that the price of the guitar was less than $602. This doesn't matter. If the price of the guitar is less than $602, then getting the TOTAL cost to $624, would require an even greater sales tax. So, we can be certain that the tax rate is GREATER than 3% Since we can answer the target question with certainty, statement 1 is SUFFICIENT Statement 2: The sales tax for the guitar that Max purchased was less than $30. Let's test some possible cases. Case a: the sales tax is $24. This means the pretax price = $624  $24 = $600. We know that 1% of $600 is $6, which means 3% of $600 is $18. Since the actual sales tax (in this scenario) is $29, we can conclude that the tax rate is GREATER than 3% Case b: the sales tax is $4. This means the pretax price = $624  $4 = $620. We know that 1% of $620 is $6.20, which means 3% of $620 is $18.60. Since the actual sales tax (in this scenario) is $4, we can conclude that the tax rate is LESS than 3% Since we cannot answer the target question with certainty, statement 2 is NOT SUFFICIENT Answer: A Cheers, Brent

Hence A answer I have no idea why I didn't attempt the problem this way. Thank you and +1 kudos!

Only I alone is Sufficient. Answer (A)U are calculating the sales tax percent on 642. It has to be calculated on the PRICE BEFORE THE SALEX TAX was applied. Example  In ur statement one.. It should be Minimum sales tax percent = 23/ 601 * 100
