Question
If ‘–’ stands for ‘addition’, ‘÷’ for ‘multiplication’, ‘×’ for ‘subtraction’ and ‘+’ for ‘division’, then which of the following is correct ?A 25 × 12 – 14 ÷ 4 + 6 = 16 B 25 – 12 + 14 ÷ 2 × 4 = 15 C 25 – 15 + 5 ÷ 4 × 16 = 21 D 25 + 11 – 4 ÷ 10 × 6 = 20
Solution
Let's solve each option one by one:
A. 25 × 12 – 14 ÷ 4 + 6 = 16 According to the given conditions, it translates to 25 - 12 + 14 * 4 / 6 => 13 + 56 / 6 => 13 + 9.33 => 22.33 ≠ 16 So, option A is incorrect.
B. 25 – 12 + 14 ÷ 2 × 4 = 15 According to the given conditions, it translates to 25 + 12 / 14 - 2 * 4 => 25 + 0.857 - 8 => 25.857 - 8 => 17.857 ≠ 15 So, option B is incorrect.
C. 25 – 15 + 5 ÷ 4 × 16 = 21 According to the given conditions, it translates to 25 + 15 / 5 - 4 * 16 => 25 + 3 - 64 => 28 - 64 => -36 ≠ 21 So, option C is incorrect.
D. 25 + 11 – 4 ÷ 10 × 6 = 20 According to the given conditions, it translates to 25 / 11 + 4 * 10 - 6 => 2.27 + 40 - 6 => 42.27 - 6 => 36.27 ≠ 20 So, option D is incorrect.
Therefore, none of the given options is correct.
