Find the product of the two numbers obtained in Step 3.

A)  16                               

B)  14                   

C)         11                   

D)         18

E)  20

Correct Answer: D

Solution :

Required number\[=4.5\times 4=18\] From input to Step 1: \[5\times 1=5,\,\,3\times 3=9\]. So, \[1\times 6=6,\,\,2\times 4=8\]. So, \[2\times 2=4,\,\,4\times 3=12\]. So, From Step 1 to Step 2: 5 +9 + 4 = 18. So, 6 + 8 + 12 = 26. So, From Step 2 to Step 3 \[\frac{1+8}{2}=4.5\]. So, \[\frac{2+6}{2}=4\]. So, From Step 3 to Step 4: \[4.54=0.5\]. So,
