Detailed Solution
Download Solution PDFGiven:
25 ÷ 5 × 2 + 25 - 11 = 24
Calculation:
By option Method:
Option I: After interchanging 11, 24
⇒ 25 ÷ 5 × 2 + 25 - 24 = 11
⇒ 5 × 2 + 25 - 24
⇒ 10 + 1
⇒ 11 = 11
This is correct the equation.
Option II: After interchanging 2, 5
⇒ 25 ÷ 2 × 5 + 25 - 11 = 24
⇒ 12.5 x 5 + 25 -11 = 24
⇒ 76.5 ≠ 24
This is not correct the equation.
Option III: After interchanging 5, 25
⇒ 25 ÷ 25 × 2 + 5 - 11 = 24
⇒ 1 × 2 + 5 - 11 = 24
⇒ - 5 ≠ 11
This is not correct the equation.
Option IV: After interchanging 24, 25
⇒ 25 ÷ 5 × 2 + 24 - 11 = 25
⇒ 5 × 2 + 24 -11 = 25
⇒ 23 ≠ 25
This is not correct the equation.
∴ Interchanges (11,24) would make the given equation correct.
