Given equation : 12 ÷ 72 × 3 - 13 = 5

Now, by interchanging the numbers

12 ÷ 72 × 3 - 5 = 13

0.16 × 3 - 5 = 13

0.48 - 5 = 13

-4.52 ≠ 13 (LHS ≠ RHS)

12 ÷ 72 × 13 - 3 = 5

0.16 × 13 - 3 = 5

2.08 - 3 = 5

-0.92 ≠ 5 (LHS ≠ RHS)

3 ÷ 72 × 12 - 13 = 5

0..4 × 12 - 13 = 5

48 - 13 = 5

35 ≠ 5 (LHS ≠ RHS)

72 ÷ 12 × 3 - 13 = 5

6 × 3 - 13 = 5

18 - 13 = 5

5 = 5 (LHS = RHS)

Hence, "Option - (4)" is the correct answer.
