If p is a prime number greater than 2, what is the value of p?

(1) There are a total of 100 prime numbers between 1 and p+1.

(2) There are a total of p prime numbers between 1 and 3,912.

Please explain.

IMO answer is D.

In DS you dont have to calculate the answer but to determine if it is possible to find the answer from given information. Lets see.. St1: this tells you that p is 100th prime number and certainly possible to calculate. like 1st prime number is 2, 2nd is 3 and so on

Statutory warning: Trying to canculate it in reat GMAT test can be injurious to health St1 sufficient.

St2:again it is possible to calculate how manny prime numbers are there between 1 and 3,912............sufficient

DS is actually a time savor since only thing we have to determine is if the given information is sufficient to find an answer.

Hey good stratergy but you always have the risk of running straight intothe famous gmat traps so one has to be extra arefull while on 1 is guessing that to reconfirm the answer.............I generally revisit the steps jst to confirm if this is not the trap where i am falling

Me too is very cautious abt those traps and most of the time confirm the answer with some calculative steps. thx for reminding me again apurva, GMAT doesn't have room for complecency.
