Which two signs should be interchanged to make the following equation correct?
139 + 40 ÷ 5 - 168 × 3 = 283
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. ÷ and ×.
Given equation: 139 + 40 ÷ 5 - 168 × 3 = 283
After interchanging the signs;
139 + 40 × 5 - (168 ÷ 3) = 283
⇒ 139 + (40 × 5) - 56 = 283
⇒ 139 + 200 - 56 = 283
⇒ 339 - 56 = 283
