Option 3 : 6 + 5 × 2 – 3 = 7

3 and 5 interchange then,

1) 5 + 3 – 4 × 2 = -1

5 + 3 – 8 = -1

8 – 8 = -1

0 = -1.

2) 1 + 9 ÷ 5 + 3 = 9

1 + 1.8 + 3 = 9

5.8 = 9

3) 6 + 3 × 2 – 5 = 7

6 + 6 – 5 = 7

12 – 5 = 7

7 = 7.

4) 3 + 4 – 1 × 5 = 2

5 + 4 - 1 × 3 = 2

5 + 4 - 3 = 2

9 - 3 = 2

6 = 2 (not equal)

So, option 3 is true hence no need to check 4th option.

Thus, the correct answer is “6 + 5 × 2 – 3 = 7”.
