Detailed Solution
Download Solution PDFAccording to the question, after interchanging the number 3 and 8:
So,
- Option - (1) : 7 + 3 – 4 ÷ 2 × 8 = 9
7 + 8 – 4 ÷ 2 × 3 = 9
7 + 8 - 2 × 3 = 9
7 + 8 - 6 = 9
15 - 6 = 9
9 = 9 (LHS = RHS)
- Option - (2) : 6 ÷ 2 × 8 + 3 – 1 = 17
6 ÷ 2 × 3 + 8 – 1 = 17
3 × 3 + 8 – 1 = 17
9 + 8 – 1 = 17
17 - 1 = 17
16 17 (LHS RHS)
- Option - (3) : 8 – 3 + 6 × 2 ÷ 4 = –2
3 – 8 + 6 × 2 ÷ 4 = –2
3 – 8 + 6 × 0.5 = -2
3 + 3 - 8 = -2
6 - 8 = -2
-2 = -2 (LHS = RHS)
- Option - (4) : 2 + 3 – 6 ÷ 2 × 8 = 1
2 + 8 – 6 ÷ 2 × 3 = 1
2 + 8 – 3 × 3 = 1
2 + 8 - 9 = 1
10 - 9 = 1
1 = 1 (LHS = RHS)
