Question

If abcd is 10 bcd is 9 then what is acd?

Answer 1

Answer:

7

Step-by-step explanation:

abcd are four letters

a = 1, b = 3, c =3 d= 3

Total = 10

bcd are three letters B=3 C=3 D=3

Total = 9

acd = 3 + 3 + 1

=7

Answer 2

If abcd is $10$ bcd is $9$ then acd is $8$

Step-by-step explanation:

Given: abcd is $10$ and bcd is $9$

To find: What is acd?

Concept/formula used:

abcd comprises of four letters

Sum of letters in abcd is $10$

$a+b+c+d=10$

bcd comprises of three letters

sum of letters in bcd is $9$

$b+c+d=9$

By solving the above two equations , we'll get the value of $a=1$

Now , if we see , above values are the sum of ranks of alphabets

So, $a=1;b=2;c=3;d=4$

Hence , value of acd$=a+c+d$

acd $=1+3+4=8$

So, value of acd is $8$
