A shop sells all kinds of school lab equipment. One school's administration bought 'X' total pieces of equipment from this shop - and these include some beakers, some flasks and rest burners. A beaker costs $2 each, each flask costs $7 and each burner costs $4. How many flasks did the school administration purchase from the shop, if there is at least one beaker, one flask and one burner purchased?
(1) X < 8.
(2) Total cost of X pieces of equipment is $27.
(1) X < 8.
(2) Total cost of X pieces of equipment is $27.

Stat 1) X<8, not suff ,as we can have multiple values of #Flasks
Stat 2) given total cost = 27$; $2*(#Beaker) + $7*(#Flasks) + $4*(#Burner) = 27$
There can be only two values of #flask 1 and 3 for above condition to satisfy
let there be 2# of flask , then 2*(#Beaker) + 14 + 4*(#Burner)= 27 ; 2*(#Beaker) + 4*(#Burner) = 13 ; LHS is even and Rhs is odd (not possible, as # should be integer and given that atleast one of each items was purchased)
so Not suff
Combined 1 & 2) still cannot find the #flask as it can be 1 or 3

Hi,
In this question, can't the 2nd condition be true where:
Given: 27= 2(Units of Beaker) + 7(Units of Flask) + 4(Units of Burner)
Now, Units of Flask can be either 1 OR 2. If Units of Flask = 2 is not possible (Total of rest would be 11 and Units of beaker and Units of burner need to be integers)
But, what about the scenario where, Units of Flask is 1. Then the values of Units of Beaker = 4 & Units of Burner = 3 satifyies the condition and gives us the answer as 1.
That's why, IMO, B is the answer.
What am I missing here?
