can someone please help on this one?

PROFIT = SELLING PRICE - COST
this is the main rule here
he question is P(x)>P(Y)?

(1)
Expences (costs) (X) = 5/6 * Expences (Y)
Nothing about profit of X and Y
ISUFFICIENT

(2)
Revenues (cost+profit margin) (X) = Revenues (Y) - 6 mill
Nothing about costs of X and Y
ISUFFICIENT

(1) and (2)
from (1) we know the ratio
from (2) we know the difference
It is not comparable things
ISUFFICIENT

ANSWER E

Thanks a lot! After your explanation, I tried to put both together using equations and they had 2 diff variables, neither of which could be solved for a value to get the other.

x = (5/6) * Y

X = Y - 6MM
