By interchanging the given two signs and numbers which of the following equation will be not correct?
× and –, 8 and 4
I. 4 + 3 × 8 – 2 ÷ 1 = 3
II. 8 × 2 – 4 + 6 ÷ 2 = 11
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. Only II.
Given conditions: × and –, 8 and 4
After interchanging the expression becomes:
I. 8 + 3 - 4 × 2 ÷ 1 = 3
= 8 + 3 - 4 × 2
= 8 + 3 - 8
= 3 is equal to 3
II. 8 × 2 – 4 + 6 ÷ 2 = 11
= 4 - 2 × 8 + 6 ÷ 2
= 4 - 2 × 8 + 3
= -9 is not equal to 11
