Which two signs need to be interchanged to make the following equation correct?
31 + 69 ÷ 23 × 5 − 83 = 99
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. − and +.
Given equation: 31 + 69 ÷ 23 × 5 − 83 = 99
On interchanging the signs:
31 - 69 ÷ 23 × 5 + 83 = 99
31 - 15 + 83 = 99
114 - 15 = 99
99 = 99
