x, a, z, and b are single digit positive integers. x = ¼ a. z = ¼ b. (10a + b) + (10x + z) could be equal to  Choose the correct choice from the following options:
A) 33
B) 36
C) 44
D) 63
E) 95
1) firstly we are not given that all are different integers..   2) since each is a positive single digit integer and x=a/4... a can take only 4 and 8 as value, and x can take 1 and 2..   3) same as 2) for b and z.   so in (10a + b) + (10x + z) ..   10a+b can be   44,48,84,88..   10x+z can be   11,12,21,22..   ans 95
