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
 Find the correct group of signs to solve the equation.

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).
 If '+' means '', '', means 'x' , '÷' means '+' and 'x' means '÷', then

? = 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

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