Detailed Solution
Download Solution PDFGiven equation : 50 * 10 * 20 * 5 * 105
According to the question, by replacing the * signs:
So,
- Option - (1) : ÷, ×, +, =
50 ÷ 10 × 20 + 5 = 105
5 × 20 + 5 = 105
100 + 5 = 105
105 = 105 (LHS = RHS)
- Option - (2) : ×, -, +, =
50 × 10 - 20 + 5 = 105
500 + 5 - 20 = 105
505 - 20 = 105
485 ≠ 105 (LHS ≠ RHS)
- Option - (3) : ÷, ×, -, =
50 ÷ 10 × 20 - 5 = 105
5 × 20 - 5 = 105
100 - 5 = 105
95 ≠ 105 (LHS ≠ RHS)
- Option - (4) : ×, ÷, +, =
50 × 10 ÷ 20 + 5 = 105
50 × 0.5 + 5 = 105
25 + 5 = 105
30 ≠ 105 (LHS ≠ RHS)
Hence, "Option - (1)" is the correct answer.
