Which two signs should be interchanged to make the given equation correct?
24 ÷ 4 + 50 – 20 × 6 = 35
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. ÷ and –.
Given equation: 24 ÷ 4 + 50 – 20 × 6 = 35
Option 1: × and –
After interchanging the expression becomes:
= 24 ÷ 4 + 50 × 20 - 6 = 35
= 6 + 50 × 20 - 6
= 6 + 1000 - 6
= 1000 is not equal to 35.
Option 2: + and –
After interchanging the expression becomes:
= 24 ÷ 4 - 50 + 20 × 6 = 35
= 6 - 50 + 20 × 6
= 6 - 50 + 120
= 76 is not equal to 35.
Option 3: ÷ and –
After interchanging the expression becomes:
= 24 - 4 + 50 ÷ 20 × 6 = 35
= 24 - 4 + 15
= 35 is equal to 35.
As we have found our answer, so, there is no need of checking other options.
Hence, option 3 is the correct answer.
