Question

Which two signs should be interchanged to make the given equation correct?

4 × 7 + 36 - 12 ÷ 6 = 25

1. ÷ and ×
2. × and -
3. ÷ and -
4. + and -

Answer 1

Correct Answer - Option 3 : ÷ and -

Given,

4 × 7 + 36 - 12 ÷ 6 = 25

Hereby putting options

1) ÷ and × 

 4 ÷ 7 + 36 - 12 × 6 = 25

0.57 + 36 - 12 × 6 = 25

0.57 + 36 - 72 = 25

36.57 - 72 = 25

-35.43 ≠ 25

2) × and - 

4 - 7 + 36 × 12 ÷ 6 = 25

4 - 7 + 36 × 2 = 25

4 - 7 + 72 = 25

69 ≠ 25

3) ÷ and -  

4 × 7 + 36 ÷ 12 - 6 = 25

4 × 7 + 3 - 6 = 25

28 + 3 - 6 = 25

28 - 3 = 25

25 = 25

4) + and -  

4 × 7 - 36 + 12 ÷ 6 = 25

4 × 7 - 36 + 3 = 25

28 - 36 + 3 = 25

31 - 36 = 25

- 5 ≠ 25

Hence, the correct answer is ÷ and -
