Detailed Solution
Download Solution PDFThe logic followed here is:
Logic: (Cube of 1st number) × 3 - 2 = 2nd number.
Now,
6 : 646
→ 63 × 3 - 2
→ 216 × 3 - 2
→ 648 - 2 = 646.
4 : 190
→ 43 × 3 - 2
→ 64 × 3 - 2
→ 192 - 2 = 190.
Similarly, 5 : ?
→ 53 × 3 - 2
→ 125 × 3 - 2
→ 375 - 2 = 373.
Hence, the correct answer is "373".
Alternate Method
Logic : (Cube of 1st number) × 3 = 2nd number + 2
So,
- 6 : 646
216 × 3 = 648
648 = 648 (LHS = RHS)
And,
- 4 : 190
64 × 3 = 192
192 = 192 (LHS = RHS)
Similarly,
- 5 : ?
125 × 3 - 2 = ?
375 - 2 = ?
373 = ?
Hence, "373" is the correct answer.
