C) 9
D) 7
E) None of these
View Answer
Option E
Solution:
Required average =(1+3+5)/3 = 3

Directions (6-10): A string of numbers is given as input. The further steps given are obtained by applying certain logic. Numbers of step II have been obtained by using at least 1 digit of each number in step I. Each step is a resultant of previous step only.

Input:

1. What is the average of numbers obtained in last 2 steps?
A) 8
B) 5
C) 3
D) 6
E) 4
View Answer
Option E
Solution:
Step 1:  85……….76……..96  —- Multiplication

Step 2:         24……….17  —– Addition   (8+7+9 = 24, 5+6+6 = 17)
Step 3:           2………..6  —— Subtraction
Step 4:                 4    —– Average
Required Average = (2+6+4)/3 = 12/3 = 4
