Question
If '-‘ stands for division '+' stands for subtraction ‘÷' stands for multiplication ‘x' stands for addition, then which one of the following equations is correct?
Answer: Option B
Answer: (b)
- ⇒ ÷, + ⇒ x, ÷ ⇒ x, - ⇒ +,
From option (a),
70 - 2 + 4 ÷ 5 x 6 = 44
⇒ 70 ÷ 2 - 4 x 5 + 6 = 44
⇒ 35 - 20 + 6 ≠ 44
From option (b),
70 - 2 + 4 ÷ 5 x 6 = 21
⇒ 70 ÷ 2 - 4 x 5 + 6 = 21
⇒ 35 - 20 + 6 = 21
⇒ 41 - 20 = 21
Therefore 21 = 21
As,we got our answer, there is no need to check option (c) & (d).
