   A.) 5.4
   B.) 14.4
   C.) -5.6
   D.) 4.4

Answer: Option 'D'

Given,A is coded as -,
B is coded as +,
C is coded as * and
D is coded as /
and the given expression:7 A 5 B 2 C 2 D 5 C 3
By using correct symbols, we get,
7 - 5 + 2 * 2 / 5 * 3
= 4.4

Answer: Option 'C'

Given,* stands for '+',
/ stands for '-',
+ stands for '*', and
- stands for '/'

and the given expression:20 * 8 / 8 - 4 + 2
By using correct symbols, we get,
20 + 8 - 8 / 4 * 2
= 24

3.

   C.) 12
   D.) 14

Answer: Option 'A'

Given,'+' means '/',
'/' means '*',

and the given expression:(13 - 5 * 8 + 4) * (5 - 6 + 12 * 3) / (4 + 2)
By using correct symbols, we get,
(13 + 5 - 8 / 4) - (5 + 6 / 12 - 3) * (4 / 2)
= 11

4.

In a certain code language, '+' means '*', '*' means '-', '-' means '/' and '/' means '+', then find the value of 9 + 4 - 6 * 6 / 8

   A.) 4
   B.) 5
   C.) 6
   D.) 8

Answer: Option 'D'

Given,'+' means '*',
'*' means '-',
'-' means '/' and
'/' means '+'

and the given expression: 9 + 4 - 6 * 6 / 8
By using correct symbols, we get,
9 * 4 / 6 - 6 + 8
= 8

5.

If A is coded as -, B is coded as +, C is coded as * and D is coded as / then evaluate 7 A 4 B 8 C 10 D 4 C 5?

   A.) 104
   B.) 113
   C.) 103
   D.) 123

Answer: Option 'C'

Given,A is coded as -,
B is coded as +,
C is coded as * and
D is coded as /
and the given expression: 7 A 4 B 8 C 10 D 4 C 5
By using correct symbols, we get,
7 - 4 + 8 * 10 / 4 * 5
= 103
