By interchanging the given two signs and numbers which of the following equation will be not correct?
× and ÷, 2 and 6
I. 7 – 4 × 3 ÷ 6 + 2 = 8
II. 6 – 8 × 2 + 9 ÷ 3 = 5
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. Both I and II.
Given conditions: × and ÷, 2 and 6
After interchanging the expression becomes:
I. 7 – 4 × 3 ÷ 6 + 2 = 8 = 7 – 4 ÷ 3 × 2 + 6
= 10.33 is not equal to 8.
II. 6 – 8 × 2 + 9 ÷ 3 = 5
2 – 8 ÷ 6 + 9 × 3 ⇒ 27.66 = 5
