Mr. Jones spends $76 on movie tickets for a group of adults and children. How many children’s tickets did he purchase? (1) Adult movie tickets cost$ 11 each and children’s movie tickets cost $7 each. (2) Mr. Jones bought two more adult tickets than children’s tickets. (1) 11a + 7c=76 --> $$c=\frac{76-11a}{7}$$, so we have here a unique combination a=5, c=3 Sufficient (2) Clearly not sufficient, as we don't know the total amount Answer A We know the total 76$ so D
5 & 3 resp

Hi,
you may know the total amount and the info that there are 2 more adult tickets than children's tickets..
but till we know some relation or values of individual tickets, we cannot say anything about the final number..
you are unconsciously carrying forward the info of statement 1 to statement 2..
so 2 is not sufficient..

With statement B, we don't know the prices of each ticket.

(1) Adult movie tickets cost $11 each and children’s movie tickets cost$ 7 each.
(2) Mr. Jones bought two more adult tickets than children’s tickets.

#1
11x+7y= 76
so
x=5 & y =3 sufficient
#2
x=2y
insufficient
IMO A
