Question
If ‘-’ stands for division, '+' for multiplication, '÷' for subtraction and ‘x' for addition, then which one of the following equations is correct?
Answer: Option C
Answer: (c)
- ⇒ ÷, + ⇒ x, ÷ ⇒ x, - ⇒ +,
From option (a), 19 + 5 - 4 x 2 ÷ 4 = 11
⇒ 19 x 5 ÷ 4 + 2 - 4 = 11
⇒ 95/4 + 2 - 4 ≠ 11
From option (b),
19 x 5 - 4 ÷ 2 + 4 = 16
⇒ 19 + 5 ÷ 4 - 2 x 4 = 16
⇒ 19 + 5/4 - 8 ≠ 16
From option (c),
19 ÷ 5 + 4 - 2 x 4 = 13
⇒ 19 - 5 x 4 ÷ 2 + 4 = 13
⇒ 19 - 5 x 2 + 4 = 13
⇒ 19 - 10 + 4 = 13
Therefore 13 = 13
As,we got our answer, there is no need to check option (d).
