According to the question, after interchanging the signs:
So,
- Option - (1) : − and ×
34 ÷ 16 + 4 - 8 × 6 = 60
2.125 + 4 - 8 × 6 = 60
2.125 + 4 - 48 = 60
6.125 - 48 = 60
-41.875 ≠ 60 (LHS ≠ RHS)
- Option - (2) : + and ×
Given statement : 34 ÷ 16 + 4 * 8 − 6 = 60
After interchanging:
34 ÷ 16 × 4 + 8 − 6 = 60
2.125 × 4 + 8 − 6 = 60
8.5 + 8 - 6 = 60
16.5 - 6 = 60
10.5 ≠ 60 (LHS ≠ RHS)
- Option - (3) : ÷ and −
Given statement : 34 ÷ 16 + 4 * 8 − 6 = 60
After interchanging:
34 - 16 + 4 × 8 ÷ 6 = 60
34 - 16 + 4 × 1.33 = 60
34 + 5.32 - 16 = 60
39.32 - 16 = 60
23.32 ≠ 60 (LHS ≠ RHS)
- Option - (4) : ÷ and +
Given statement : 34 ÷ 16 + 4 * 8 − 6 = 60
After interchanging:
34 + 16 ÷ 4 × 8 − 6 = 60
34 + 4 × 8 − 6 = 60
34 + 32 - 6 = 60
66 - 6 = 60
60 = 60 (LHS = RHS)
Hence, "Option - (4)" is the correct answer.
