Detailed Solution
Download Solution PDFHere, we use the BODMAS table given below:
Given:
⇒ 11 * 13 * 238 * 17 * 34 = 123
(1) + × - ÷
⇒ 11 * 13 * 238 * 17 * 34 = 123
After Putting the signs:
⇒ 11 + 13 × 238 - 17 ÷ 34 = 123
Apply BODMAS rule:
⇒ 11 + 13 × 238 - 0.5
⇒ 11 + 3094 - 0.5
⇒ 3105 - 0.5 = 3104.5
Here, the equation is not satisfied.
(2) × + ÷ -
⇒ 11 * 13 * 238 * 17 * 34 = 123
After Putting the signs:
⇒ 11 × 13 + 238 ÷ 17 - 34 = 123
Apply BODMAS rule:
⇒ 11 × 13 + 14 - 34
⇒ 143 + 14 - 34
⇒ 157 - 34 = 123
Here, the equation is satisfied.
(3) + ÷ × -
⇒ 11 * 13 * 238 * 17 * 34 = 123
After Putting the signs:
⇒ 11 + 13 ÷ 238 × 17 - 34 = 123
Apply BODMAS rule:
⇒ 11 + 0.054 × 17 - 34
⇒ 11 + 0.928 - 34
⇒ 11.928 - 34 = (-22.07)
Here, the equation is not satisfied.
(4) ÷ - + ×
⇒ 11 * 13 * 238 * 17 * 34 = 123
After Putting the signs:
⇒ 11 ÷ 13 - 238 + 17 × 34 = 123
Apply BODMAS rule:
⇒ 0.846 - 238 + 17 × 34
⇒ 0.846 - 238 + 578
⇒ 578.846 - 238 = 340.84
Here, the equation is not satisfied.
Hence, the correct answer is "Option (2)".
