Detailed Solution
Download Solution PDFLet's check each option,
1) + and ×
→ 561 ÷ 11 + 22 × 6 – 25 = 158
→ 51 + 22 × 6 – 25 = 158
→ 51 + 132 – 25 = 158
→ 183 – 25 = 158
→ 158 = 158
→ LHS = RHS
2) ÷ and ×
→ 561 × 11 ÷ 22 + 6 – 25 = 158
→ 561 × 1/2 + 6 – 25 = 158
→ 280.5 + 6 – 25 = 158
→ 286.5 – 25 = 158
→ 261.5 ≠ 158
→ LHS ≠ RHS
3) ÷ and +
→ 561 + 11 × 22 ÷ 6 – 25 = 158
→ 561 + 11 × 11/3 – 25 = 158
→ 561 + 121/3 – 25 = 158
→ 601 - 25 ≠ 158
→ LHS ≠ RHS
4) + and –
→ 561 ÷ 11 × 22 - 6 + 25 = 158
→ 51 × 22 - 6 + 25 = 158
→ 1122 - 6 + 25 = 158
→ 1147 - 6 = 158
→ 1141 ≠ 158
→ LHS ≠ RHS
Here, we can see that only Option 1 gives the correct equation.
Hence, the correct answer is "+ and ×".
