Correct option is D
Given: 12+ 6 × 2 - 24 ÷ 8 = 3
Form the option-
(a) × and – interchanging the sign we get following equation-
12+ 6 - 2 × 24 ÷ 8 = 3 (Apply the BODMAS rule)
12+ 6 - 2 × 3 = 3
12+ 6 - 6 = 3
18 - 6 = 3
12 ≠ 3
(b) - and = interchanging the sign we get following equation-
12+ 6 × 2 = 24 ÷ 8 – 3 (Apply the BODMAS rule)
12+ 6 × 2 = 3 – 3
12+ 12 = 3 – 3
24 = 3 – 3
24 ≠ 0
(c) ÷ and - interchanging the sign we get following equation-
12+ 6 × 2 ÷ 24 - 8 = 3 (Apply the BODMAS rule)
12+ 6 × 1/12 - 8 = 3
12+ 0.5 - 8 = 3
12.5 - 8 = 3
4.5 ≠ 3
(d) + and - interchanging the sign we get following equation-
12 - 6 × 2 + 24 ÷ 8 = 3 (Apply the BODMAS rule)
12 - 6 × 2 + 3 = 3
12 - 12 + 3 = 3
15 - 12 = 3
3 = 3
Thus, the correct answer is (d) + and -
