Question

If 1 is subtracted from each odd digit and 2 is added to each even digit in the number '2965413'. What will be the average of the largest and smallest digits thus formed?

A.

8

B.

2

C.

6

D.

4

Correct option is D

Given: 2965413
Subtract 1 from each odd digit:
9 - 1 = 8; 5 - 1 = 4; 1 - 1 = 0; 3 - 1 = 2
Add 2 to each even digit:
2 + 2 = 4; 6 + 2 = 8; 4 + 2 = 6
So, the number formed is '4884602'.
The largest digit is 8, and the smallest digit is 0.
Average = (8 + 0) ÷\div 2 = 8 ÷\div 2 = 4
So, the correct answer is (d).
