Which two numbers need to be interchanged to make the following equation correct?
15 × 7 + 64 – 80 ÷ 16 = 181
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4, i.e., 64 and 80.
After interchanging numbers,
15 × 7 + 80 – (64 ÷ 16) = 181
105 + 80 - 4 = 181
105 + 76 = 181
181 = 181
