Correct Answer: + - =
Explanation:
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).
Correct Answer: = ÷ - +
Explanation:
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
Correct Answer: 3 ? 6 ? 2 ? 8 ? 4 ? 5
Explanation:
Given question is,
3 ? 6 ? 2 ? 8 ? 4 ? 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
Correct Answer: 27
Explanation:
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
Correct Answer: 4A 3M 2L 4D 2M 6
Explanation:
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
Correct Answer: 28
Explanation:
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
Correct Answer: 53
Explanation:
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
