Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFThe logic followed here is : (1st number × 3rd number) + 3rd number = 2nd number
Given :
- (8, 540, 60)
8 × 60 + 60 = 540
480 + 60 = 540
540 = 540 (LHS = RHS)
- (9, 70, 7)
9 × 7 + 7 = 70
63 + 7 = 70
70 = 70 (LHS = RHS)
So,
- Option - (1) : (12, 56, 60)
12 × 60 + 60 = 56
720 + 60 = 56
780 ≠ 56 (LHS ≠ RHS)
- Option - (2) : (8, 63, 7)
8 × 7 + 7 = 63
56 + 7 = 63
63 = 63 (LHS = RHS)
- Option - (3) : (9, 54, 12)
9 × 12 + 12 = 54
108 + 12 = 54
120 ≠ 54 (LHS ≠ RHS)
- Option - (4) : (9, 45, 7)
9 × 7 + 7 = 45
63 + 7 = 45
70 ≠ 45 (LHS ≠ RHS)
Hence, "Option - (2)" is the correct answer.
