After interchanging the given two numbers and two signs what will be the values of equations (I) and (II) respectively?
× and ÷, 7 and 9
I. 8 × 3 ÷ 6 + 9 – 7
II. 9 – 7 × 1 + 6 ÷ 3
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 14, 16.
Given conditions: × and ÷, 7 and 9
I. 8 × 3 ÷ 6 + 9 – 7
After interchanging the expression becomes:
= 8 ÷ 3 × 6 + 7 – 9 = 14
II. 9 – 7 × 1 + 6 ÷ 3
After interchanging the expression becomes:
= 7 – 9 ÷ 1 + 6 × 3
= 7 – 9 + 6 × 3 = 16
