Question

If DISC is coded as 8749 and ACHE is coded as 3950 , then HEAD is coded as (answer 5308,3508,3805,5038)

Answer 1

5038 because each example such as disc means 8749
D=8
I=7
S=4
C=9
D will represent the numeric 8 only I will represent 7 only S will represent 4 only and C will represent 9only
Similarly with ACHE as 3950
A=3
C=9
H=5
E=0
And by taking each word representing each numeric we have
H=5
E=0
A=3
D=8

Answer 2

We should prepare a table.

A=3
C=9
D=8
E=0
H=5
I=7

Here we can derive HEAD.

H=5 E=0 A=3 D=8.

Ans: HEAD⇒5·0·3·8
