Detailed Solution
Download Solution PDFGiven equation : 25 × 5 ÷ 6 + 20 = 62 − 12
According to the question, after interchanging the mathematical signs:
So,
- Option - (1) : + and ÷
25 × 5 ÷ 6 + 20 = 62 − 12 ⇒ 25 × 5 + 6 ÷ 20 = 62 − 12
25 × 5 + 0.3 = 50
125 + 0.3 = 50
125.3 ≠ 50 (LHS ≠ RHS)
- Option - (2) : ÷ and ×
25 × 5 ÷ 6 + 20 = 62 − 12 ⇒ 25 ÷ 5 × 6 + 20 = 62 − 12
5 × 6 + 20 = 50
30 + 20 = 50
50 = 50 (LHS = RHS)
- Option - (3) : + and −
25 × 5 ÷ 6 + 20 = 62 − 12 ⇒ 25 × 5 ÷ 6 - 20 = 62 + 12
25 × 0.83 - 20 = 74
20.75 - 20 = 74
0.75 ≠ 74 (LHS ≠ RHS)
- Option - (4) : + and ×
25 × 5 ÷ 6 + 20 = 62 − 12 ⇒ 25 + 5 ÷ 6 × 20 = 62 − 12
25 + 0.83 × 20 = 50
25 + 16.6 = 50
41.6 ≠ 50 (LHS ≠ RHS)
