After interchanging the given two numbers what will be the values of equation (I) and (II) respectivly?
7 and 8
I. 5 × 7 + 6 ÷ 2 - 8
II. 8 + 3 × 7 - 5 ÷ 1
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 36 and 26.
I. 5 × 7 + 6 ÷ 2 - 8
After interchanging number
= 5 × 8 + (6 ÷ 2) - 7
= 40 + 3 - 7
= 43 - 7 = 36.
Similarly,
II. 8 + 3 × 7 - 5 ÷ 1
= 7 + 3 × 8 - (5 ÷ 1)
= 7 + 24 - 5
= 31 - 5 = 26
