By interchanging the given two signs and numbers which of the following equation will be correct?
× and +, 6 and 4
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 7 × 6 – 4 + 9 ÷ 3 = –7.
Given conditions × and +, 6 and 4
Option 1: 7 × 6 – 4 + 9 ÷ 3 = –7
After interchanging the expression becomes:
7 + 4 – 6 × 9 ÷ 3 = –7
7 + 4 – 6 × 3 = –7
7 + 4 – 18 = –7
11 - 18 = –7
-7 = -7
