p is directly proportional to e which is directly proportional to i
we can say
p is also directly proportional to i

Statement 1: In the first statement there is no mention about the variable p. Therefore BCE

Statement 2: I used unitary method.
If i=50 when p=2
When i=70 p=2*70/50

This statement gives a unique solution. Therefore B.

p=Ke ( K being a constant)
e=Li ( L beinga constant)
combining the above 2 p=KLi
1. clearly insufficient as it does not helps at all
2. Clearly sufficient P=70Li as L could be found from 2 and put in the main equation to find the answer.
B
