Solution

Average = $\frac{total sum of elements}{number of elements}$

Average of 5 numbers = 34.4

total of 5 numbers= 34.4 x 5 = 172

Similarly total sum of 1st and 2nd number = 46.5 x 2 = 93

Similarly total sum of 4th and 5th number = 18 x 2 = 36

3rd Number = 172 - (93+36) = 43

hence , E option is correct
