Was the price of a certain stereo in March greater than its price in May?

(1) The price of the stereo in March was 80 percent of its price in April.

(2) The price of the stereo in April was 120 percent of its price in May

Given to find P(mar) > P(May) ?

Stat 1: let the price be 100 then

P(mar) = 80 ; and P(Apr) = 100.... Insufficient to relate Mar and May...

Stat 2: P(Apr) is 120% P(May)....Insufficient to relate Mar and May...

Stat 1 + Stat 2: If we 80(Mar) , 100 (Apr) and may value is less than 120% of April...as per our case we get less than 100 i.e. some negative.

So def P(mar) > P(May) ...Sufficient...

IMO option C is correct answer...

OA please..will correct if I missed anything..
