Find number of sandwiches sold today?

(1) The number of sandwiches sold yesterday is 12 fewer than half of that sold today.
Let sandwiches sold yesterday = y
sandwiches sold today = t

so given y = (1/2)*t -12
2y=t-24
Not sufficient

(2) The number sold today is 24 more than twice the number sold yesterday.
give: t= 2*y+24
Its same as details given in point 1.
Not sufficient

As by both we don't get exact value of number of sandwiches.

let the no. of sandwiches sold today be x

(1) sold yesterday = (x/2)-12
not sufficient

(2) sold yesterday = (x-24)/2
not sufficient

on combining

(x/2) - 12 = (x-24)/2
x-24 =x-24
not sufficient

E
