Detailed Solution
Download Solution PDFLogic : (2nd number × 2) = (3rd number + 1st number)
Given :
- (9, 20, 31)
20 × 2 = 31 + 9
40 = 40 (LHS = RHS)
- (38, 49, 60)
49 × 2 = 60 + 38
98 = 98 (LHS = RHS)
So,
- Option - (1) : (63, 60, 65)
60 × 2 = 65 + 63
120 ≠ 128 (LHS ≠ RHS)
- Option - (2) : (15, 20, 31)
20 × 2 = 31 + 15
40 ≠ 46 (LHS ≠ RHS)
- Option - (3) : (25, 69, 45)
69 × 2 = 45 + 25
138 ≠ 70 (LHS ≠ RHS)
- Option - (4) : (14, 24, 34)
24 × 2 = 34 + 14
48 = 48 (LHS = RHS)
Hence, "Option - (4)" is the correct answer.
