Hello Avi2crackgmat,
We have to determine whether the product of 3p and 4 is greater than 20.
Let us consider 1)
It tells us that 5p>7.
Multiple both sides by 12/5. This would give us 12p>16.8. However, we cannot be sure of whether 12p>20 or not. It could equal to 21 or equal to 17 for all we know. Hence,INSUFFICIENT.
Let us consider statement 2).
It tells us that 3p-5>1
This implies that 3p>6. Therefore, 12p>24. Hence, we know for sure that 12p has to be greater than 20. Hence, SUFFICIENT.
Answer=B.
Hope this helps! Let me know in case of any further questions.
