Question 35

In a certain code language, ‘6532’ is written as ‘3467’. What will be the code for ‘7915’ in that code language?

Solution

6532 ==> 3467

After observing the given code, we can say that 4 <==> 5, 3 <==> 6, 2 <==> 7.

Similarly, 1 <==> 8 and 0 <==> 9.

'<==>' represents that digits can code vice versa. For example, 4 can be coded as 5 and 5 can be coded as 4.

So 7915 ==> 2084
