Question
If  43     34     x     36 Â
   39      38 Then, x/2 + 0.5 + x = ? In each of the following questions a number series is given.  One term of the series is denoted by x. You have to calculate the value of x  and by using the value of x,  you have  to replace the question mark (?) in the following questions :Solution
43 - 9 = 34 34 + 7 = 41 41 - 5 = 36 36 + 3 = 39 39 - 1 = 38 Hence, x= 41 Hence, 41/2 + 0.5 + 41Â = 20.5 + 0.5 + 41 = 62
