Which two signs and two numbers should be interchanged to make the given equation correct?
81 + 15 ÷ 5 – 23 × 27 = 95
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2, i.e., 81 and 23, ÷ and ×.
After interchanging signs and numbers,
81 + 15 ÷ 5 – 23 × 27 = 95
23 + 15 × 5 - (81 ÷ 27) = 95
23 + 75 - 3 = 95
23 + 72 = 95
95 = 95
