SSC CGL 20201)If 'A' stands for 'subtraction', 'B' stands for 'multiplication', 'C' stands for 'addition' and 'D' stands for 'division', then what is the value of the following expression ?

32 B 4 A 12 B (35 A 24) C 52 D 4

Correct Option: B

9

A ⇒ - B ⇒ x C ⇒ + D ⇒ ÷

3 2 B 4 A 12 B (35 A 24) C 52 D 4 =32 x 4 - 12 x (35-24) +52 ÷ 4, = 32 x 4 - 12 x 11 + 13, = 128 - 132 + 13, = 141 - 132, = 9

SSC CGL 20202)Which two signs should be interchanged to make the given equation correct ?

\(14\times 3\div 27+54-9=21\)

Correct Option: D

\(\div \) and -

\(14\times 3\div 27+54-9=21\); From the option D; On interchanging the \(\div\) and -, 42 - 27 + 6 = 21;

21 = 21;

SSC CGL 20203)If 'A' stands for ‘subtraction’, ‘B’ stands for 'multiplication’, ‘C’ stands for ‘addition’, and D stands for ‘division’, then what is the value of the following expression?

43 C 29 B 3 A 14 B (5C4) C 11 C (14A3) A 64 D 8 B 2

Correct Option: D

10

43 C 29 B 3 A 14 B (5C4) C 11 C (14A3) A 64 D 8 B 2;

On apply instructions,\(43+29\times3-14\times(5+4)+11+(14-3)-64\div 8\times2=10\) {A = -, B = x, C = +, D = \(\div\) }

SSC CGL 20204)Which two signs should be interchanged to make the given equation correct?

\(121\div 11+54-9\times 3 = 128\)

Correct Option: D

\(\div\) and -

\(121\div 11+54-9\times 3 = 128\); \(121- 11+54\div 9\times 3 = 128\); 128 = 128; L.H.S. = R.H.S

SSC CGL 20205)If 'A' stands for 'subtraction', 'B' stands for 'multiplication', 'C' stands for 'addition', and 'D' stands for 'division', then what is the value of the following expression?

27 A 8 B 5 C (11 C 3) B 5 C 36 D 6

Correct Option: B

63

27 A 8 B 5 C (11 C 3) B 5 C 36 D 6

On changing the alphabets,

=27 − 8 × 5 + (11 + 3) × 5 + 36 ÷ 6

=27 − 40 + (14) × 5 + 6

= 27 − 40 + 70 + 6

= 63

SSC CGL 20206)Select the correct combination of mathematical signs to sequentially replace the signs *, to balance the following equation.

(14 * 9 * 6) * 15 * 8

Correct Option: D

\(\times,-,\div,=\)

\((14 * 9 * 6) * 15 * 8=(14 \times 9 - 6) \div 15 = 8\); ⇒ 8 = 8; L.H.S = R.H.S

SSC CGL 20207)Which two numbers should be interchanged to make the given equation correct?

28 + 49 − 35 ÷ 7 × 4 = 68

Correct Option: C

28 and 35

SSC CGL 20208)The two given expressions on both the side of the ‘=’ sign will have the same value if two numbers from either side or both side are interchanged. Select the correct numbers to be interchanged from the given options.

4 + 6 × 7 − 27 ÷ 3 = 7 × 8 − 4 + 39 ÷ 3

Correct Option: D

6, 8

6 and 8 are interchanged. 4 + 6 × 7 − 27 ÷ 3 = 7 × 8 − 4 + 39 ÷ 3; ⇒

4 + 56 − 9 = 42 − 4 + 13; ⇒ 51 =51 L.H.S = R.H.S

SSC CGL 20209)Which two signs should be interchanged to make the given equation correct?

\(12+81-27\times9\div3 =36\)

Correct Option: A

− and ÷

\(12+81-27\times9\div3 =36\) From the option A,

On changing the sign, \(12+81\div27\times9-3 =36\); ⇒ 36 = 36

SSC CGL 202010)Which two signs and two numbers should be interchanged to make the given equation correct?

\(28-32\div2\times8+34=132\)

Correct Option: A

+ and - ; 32 and 34
