Detailed Solution
Download Solution PDFGiven : 150 × 15 + 14 - 9 ÷ 2 = 6
So, after interchanging two signs and two numbers :
- Option - (1) : 9, 2, -, ×
150 - 15 + 14 × 2 ÷ 9 = 6
150 - 15 + 14 × 0.22 = 6
150 + 3.08 - 15 = 6
153.08 - 15 = 6
138.08 ≠ 6 (LHS ≠ RHS)
- Option - (2) : 9, 2, ÷, ×
150 ÷ 15 + 14 - 2 × 9 = 6
10 + 14 - 2 × 9 = 6
10 + 14 - 18 = 6
24 - 18 = 6
6 = 6 (LHS = RHS)
- Option - (3) : 150, 2, ÷, -
2 × 15 + 14 ÷ 9 - 150 = 6
2 × 15 + 1.55 - 150 = 6
30 + 1.55 - 150 = 6
31.55 - 150 = 6
118 ≠ 6 (LHS ≠ RHS)
- Option - (4) : 15, 9, +, ÷
150 × 9 ÷ 14 - 15 + 2 = 6
150 × 0.64 - 15 + 2 = 6
96 + 2 - 15 = 6
98 - 15 = 6
8 ≠ 6 (LHS ≠ RHS)
