Mathematical operation and symbol notation

1. Select the correct combination of mathematical signs to replace '*' signs and to balance the given equation.
24 * 34 * 2 * 5 * 12

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. 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).

1. If '+' means '-', '-', means 'x' , '÷' means '+' and 'x' means '÷', then
10 x 5 ÷ 3 - 2 + 3 = ?

1. ? = 10 x 5 ÷ 3 - 2 + 3
= 10 ÷ 5 + 3 x 2 - 3 (by interchanging sign)

Correct Option: A

? = 10 x 5 ÷ 3 - 2 + 3
= 10 ÷ 5 + 3 x 2 - 3 (by interchanging sign)
= 2 + 3 x 2 - 3
= 2 + 6 - 3 = 8 - 3 = 5

1. If Q means '+', J means 'x', T means '-' and K means '÷' then
30 K 2 Q 3 J 6 T 5 = ?

1. Using the correct symbols, we have
30 K 2 Q 3 J 6 T 5
= 30 ÷ 2 + 3 x 6 - 5

Correct Option: B

Using the correct symbols, we have
30 K 2 Q 3 J 6 T 5
= 30 ÷ 2 + 3 x 6 - 5
= 15 + 18 - 5 = 33 - 5 = 53

1. If P denotes '÷', Q denotes 'x', R denotes '+' and S denotes '-', then
18 Q 1 2 P 4 R 5 S 6

1. Using the correct symbols, we have
18 Q 1 2 P 4 R 5 S 6
= 18 x 12 ÷ 4 + 5 - 6

Correct Option: A

Using the correct symbols, we have
18 Q 1 2 P 4 R 5 S 6
= 18 x 12 ÷ 4 + 5 - 6
= 18 x 3 + 5 - 6
= 54 + 5 - 6 = 59 - 6 = 53
