Answer : 3
Explanatory Answer
From second constraint,
OLD Visitors = x, MID = 2x, Young = 4x.
7x = 140 or, x = 20 , 2x = 40 , 4x = 80.
Let us fill this in. and then go to constraint 3 and 4.
From constraint 3, Total Platinum = 2y, then YNG platinum should be y.
From constraint 4, Let us fill OLD-GOLD and OLD-ECO has z.
OLD-PT = MID-ECO. MID-ECO = 17 – z or, OLD-PT = 17 – z.
17 – z = - 20 – 2z. Or, z = 3.
