LET us check each option one by one:Option 1) -, xGiven expression: 64 × 2 + 24 ÷ 3 - 8 = 96 After interchanging the symbols, we GET:L.H.S = 64 - 2 + 24 ÷ 3 × 8= 64 – 2 + 8 × 8= 64 – 2 + 64= 128 – 2= 126 ≠ R.H.SOption 2) +, ÷Given expression: 64 x 2 + 24 ÷ 3 - 8 = 96 After interchanging the symbols, we get:L.H.S = 64 x 2 ÷ 24 + 3 - 8= 5.33 + 3 – 8= 8.33 – 8= 0.33 ≠ R.H.SOption 3) x, ÷Given expression: 64 x 2 + 24 ÷ 3 - 8 = 96 After interchanging the symbols, we get:L.H.S = 64 ÷ 2 + 24 × 3 - 8= 32 + 72 – 8= 104 – 8= 96 = R.H.SOption 4) -, +Given expression: 64 x 2 + 24 ÷ 3 - 8 = 96 After interchanging the symbols, we get:L.H.S = 64 x 2 - 24 ÷ 3 + 8= 128 – 8 + 8= 128 ≠ R.H.SHence, ‘x, ÷’ is the correct answer.
