Given equation I. 45 + 15 × 30 ÷ 10 − 25
Now, if '+ and -' are interchanged, then:
⇒ 45 - 15 × 30 ÷ 10 + 25
⇒ 45 - 15 × 3 + 25
⇒ 45 - 45 + 25
⇒ 70 - 45 = 25.
Given equation II: 6 × 9 + 5 − 8 ÷ 4
Now, if '+ and -' are interchanged, then:
⇒ 6 × 9 - 5 + 8 ÷ 4
⇒ 6 × 9 - 5 + 2
⇒ 54 - 5 + 2
⇒ 56 - 5 = 51.
Here, the correct values are '25 and 51'.
Hence, the correct answer is "Option 1".
