Detailed Solution
Download Solution PDFGiven equation : 13 × 6 + 24 ÷ 6 - 17 = 91
Now, by interchanging the signs
- Option - (1) : ÷ and +
13 × 6 + 24 ÷ 6 - 17 = 91 ⇒ 13 × 6 ÷ 24 + 6 - 17 = 91
13 × 0.25 + 6 - 17 = 91
3.25 + 6 - 17 = 91
9.25 - 17 = 91
7.75 ≠ 91 (LHS ≠ RHS)
- Option - (2) : + and ×
13 × 6 + 24 ÷ 6 - 17 = 91 ⇒ 13 + 6 × 24 ÷ 6 - 17 = 91
13 + 6 × 4 - 17 = 91
13 + 24 - 17 = 91
37 - 17 = 91
20 ≠ 91 (LHS ≠ RHS)
- Option - (3) : ÷ and ×
13 × 6 + 24 ÷ 6 - 17 = 91 ⇒ 13 ÷ 6 + 24 × 6 - 17 = 91
2.16 + 24 × 6 - 17 = 91
2.16 + 144 - 17 = 91
146.16 - 17 = 91
129.16 ≠ 91 (LHS ≠ RHS)
- Option - (4) : + and -
13 × 6 + 24 ÷ 6 - 17 = 91 ⇒ 13 × 6 - 24 ÷ 6 + 17 = 91
13 × 6 - 4 + 17 = 91
78 + 17 - 4 = 91
95 - 4 = 91
91 = 91 (LHS = RHS)
Hence, "Option - (4)" is the correct answer.
