(1) X − Z = 400
(2) XY = 1100

Gross profit : x - y% - z.

Statement 1: No information about y%. Not sufficient.

Statement 2; No information about z. NOT sufficient.

Combining :

x - z = 400 . if we deduct y from 400 we we will get gross profit. Statement 2 gives the value of y%.

xy = 1100

x * y/100 = 1100 /100

xY% = 11.

x - z = 400

x - z - y% = 400 - 11 = 389.
