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

​$$72 - 56 + (13 + 19) \times 2 - 95 \div 5 + 17 = 76$$

(Note: Interchange should be done of the entire number and not individual digits of a given number.)

Form the given options - 

(a) 19 and 5  After interchanging the digit we get following equation- 

​$$72 - 56 + (13 + 5) \times 2 - 95 \div 19 + 17 = 76 \\ \ \\ 72 - 56 + 18 \times 2 - 5 + 17 = 76 \\ \ \\ 72 - 56 +36 - 5 + 17 = 76 \\ \ \\ 125 - 61 = 76 \\ \ \\ 64\not = 76 \\ \ \\$$ 

(b) 19 and 17 After interchanging the digit we get following equation- 

​$$72 - 56 + (13 + 17) \times 2 - 95 \div 5 + 19 = 76 \\ \ \\ 72 - 56 + (30) \times 2 - 19 + 19 = 76 \\ \ \\ 72 - 56 + 60 - 19 + 19 = 76 \\ \ \\ 151 - 75 = 76 \\ \ \\ 76 = 76 \\ \ \\$$

Thus, the correct answer is (b).
