Which two signs should be interchanged to make the given equation correct?
16 × 121 ÷ 11 + 4 − 10 = 50
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. + and ×.
Given expression: 16 × 121 ÷ 11 + 4 - 10 = 50
After interchange the mathematical sign we get;
16 + 121 ÷ 11 × 4 - 10 = 50
= 16 + 11 × 4 - 10 = 50
= 16 + 44 - 10 = 50
= 60 - 10 = 50
= 50 = 50
Hence, the correct answer is "+ and ×".
