#### Mathematical operation and symbol notation

1. If A for '+', M for 'x', D for '÷', G for '>', L for '<', then which of the following will be logically correct ?
1. 4A 5D 3G 6A 2M 3
2. 4A 5M 4L 6D 2A 8
3. 4D 2A 4G 6D 2A 4
4. 4A 3M 2L 4D 2M 6

1. Solve all option one by one.
Change the symbol in given question.
From option (D),
4 A 3 M 2 L 4 D 2 M 6
4 + 3 X 2 < 4 ÷ 2 x 6
Apply the BODMAS Rule.

##### Correct Option: D

Solve all option one by one.
Change the symbol in given question.
From option (D),
4 A 3 M 2 L 4 D 2 M 6
4 + 3 X 2 < 4 ÷ 2 x 6
Apply the BODMAS Rule.
10 < 12

1. If the mathematical signs interchange from - to +, + to ÷. x to - and ÷ to x, then find out the correct answer of the given equation
6 ÷ 8 + 2 x 5 - 8 = ?
1. 27
2. 18
3. 32
4. 28

1. Interchange the symbol as per given in question.
6 ÷ 8 + 2 x 5 - 8
After changing the sign
= 6 x 8 ÷ 2 - 5 + 8
Apply the BODMAS Rule.

##### Correct Option: A

Interchange the symbol as per given in question.
6 ÷ 8 + 2 x 5 - 8
After changing the sign
= 6 x 8 ÷ 2 - 5 + 8
Apply the BODMAS Rule.
= 6 x 4 - 5 + 8
= 24 - 5 + 8 = 32 - 5 = 27

1. If +, -, x, ÷, =, > and < are represented as δ,•, γ,η, ω, β and α respectively, then which of the following is correct?
1. 3 γ 6 η 2 δ 8 • 4 ω 5
2. 3 η 6 γ 2 δ 8 • 4 β 5
3. 3 γ 6 • 2 δ 8 η 4 α 5
4. 3 δ 6 • 2 γ 8 η 4 ω 5

1. Solve all option one by one.
Choosing the option D,
3 δ 6 • 2 γ 8 η 4 ω 5
Then, after placing of signs in given question,
3 + 6 - 2 x 8 ÷ 4 = 5
Apply the BODMAS Rule.

##### Correct Option: D

Given question is,
3 δ 6 • 2 γ 8 η 4 ω 5
Then, after placing of signs in given question,
3 + 6 - 2 x 8 ÷ 4 = 5
Apply the BODMAS Rule.
9 - 2 x 2 = 5
5 = 5

1. Select the correct combination of mathematical signs to replace '*' signs and to balance the given equation.
24 * 34 * 2 * 5 * 12
1. + ÷ x =
2. = ÷ + -
3. = ÷ - +
4. + ÷ = x

1. Solve by using all option one by one.
Use BODMAS rule to solve the equation.

##### Correct Option: C

Solve by using all option one by one.
Choosing option (C) and change the sign.
24 = 34 ÷ 2 - 5 + 12
Use BODMAS rule to solve the equation.
24 = 17 - 5 + 12
24 = 29 - 5
24 = 24

1. Find the correct group of signs to solve the equation.
24 * 16 * 8 * 32
1. ÷ - =
2. - + =
3. x ÷ =
4. + - =

1. Solve by using all option one by one.
Given equation is
24 * 16 * 8 * 32
Taking the sign of option (D),
⇒ 24 + 16 - 8 = 32
Apply the BODMAS Rule in equation.

##### Correct Option: D

Solve by using all option one by one.
Given equation is
24 * 16 * 8 * 32
Taking the sign of option (D),
⇒ 24 + 16 - 8 = 32
Apply the BODMAS Rule in equation.
⇒ 40 - 8 = 32 ⇒ 32 = 32
Hence, correct group of sign is option (b).
