Correct Answer: ÷ and −
Solution : Given: 87 − 3 + 39 ÷ 67 × 3 = −133
Interchange the given symbols in the options one by one with the original symbols in the given equation. First option: ÷ and − Solving the L.H.S. of the equation – = 87 ÷ 3 + 39 − 67 × 3 = 29 + 39 − 201 = −133 = R.H.S. Second option: × and + Solving the L.H.S. of the equation – = 87 − 3 × 39 ÷ 67 + 3 = 87 − 1.74 + 3 = 88.25 ≠ −133 Third option: × and − Solving the L.H.S. of the equation – = 87 × 3 + 39 ÷ 67 − 3 = 261 + 0.58 − 3 = 258.58 ≠ −133 Fourth option: − and + Solving the L.H.S. of the equation – = 87 + 3 − 39 ÷ 67 × 3 = 90 − 1.74 = 88.25 ≠ −133
So, only the first option satisfies the R.H.S. of the given equation. Hence, the first option is correct.
