Correct Answer: 36 and 26


Solution : Given:
7 and 8 are interchanged –
I. 5 × 7 + 6 ÷ 2 – 8 = ?
II. 8 + 3 × 7 – 5 ÷ 1 = ?

For equation I –
After interchanging the given mathematical numbers, we get –
⇒ 5 × 8 + 6 ÷ 2 – 7
⇒ 5 × 8 + 3 – 7
⇒ 40 + 3 – 7
= 36
For equation II –
After interchanging the given mathematical numbers, we get –
⇒ 7 + 3 × 8 – 5 ÷ 1
⇒ 7 + 3 × 8 – 5
⇒ 7 + 24 – 5
= 26

So, 36 and 26 are the answers to the given equations I and II respectively. Hence, the first option is correct.
