# Symbols Questions And Answers - Logical Reasoning For RRB NTPC Exams

1.

If A is coded as -, B is coded as +, C is coded as * and D is coded as / then evaluate 7 A 5 B 2 C 2 D 5 C 3?

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

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

2.

If * stands for 'addition', / stands for 'subtraction', + stands for 'multiplication', and - stands for 'division', then 20 * 8 / 8 - 4 + 2 =?

A.) 22
B.) 23
C.) 24
D.) 25

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.

In a certain code language, '+' means '/', '/' means '*', '*' means '-', '-' means '+', then find the value of (13 - 5 * 8 + 4) * (5 - 6 + 12 * 3) / (4 + 2)

A.) 11
B.) 13
C.) 12
D.) 14

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

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

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
