Detailed Solution
Download Solution PDFHere, we use the BODMAS table given below:
Given:
⇒
(1) ÷, ×, +, =, -
After Putting the signs:
⇒ 42 ÷ 7 × 5 + 5 = 40 - 5
Apply BODMAS rule:
⇒ 6 × 5 + 5 = 40 - 5
⇒ 30 + 5 = 35
⇒ 35 = 35
Here, the equation is satisfied.
(2) ÷, ×, =, +, -
After Putting the signs:
⇒ 42 ÷ 7 × 5 = 5 + 40 - 5
Apply BODMAS rule:
⇒ 6 × 5 = 45 - 5
⇒ 30 = 40
Here, the equation is not satisfied.
(3) ÷, ×, -, =, +
After Putting the signs:
⇒ 42 ÷ 7 × 5 - 5 = 40 + 5
Apply BODMAS rule:
⇒ 6 × 5 - 5 = 45
⇒ 30 - 5 = 45
⇒ 25 = 45
Here, the equation is not satisfied.
(4) +, =, ÷, ×, +
After Putting the signs:
⇒ 42 + 7 = 5 ÷ 5 × 40 + 5
Apply BODMAS rule:
⇒ 49 = 1 × 40 + 5
⇒ 49 = 40 + 5
⇒ 49 = 45
Here, the equation is not satisfied.
Hence, the correct answer is "Option (1)".
