Detailed Solution
Download Solution PDFGiven:
Sets: (4, 12, 48) and (7, 21, 84)
Formula: First number × 3 = Second number
Formula: Second number × 4 = Third number
Given (4, 12, 48):
4 × 3 = 12
12 × 4 = 48
For (7, 21, 84):
7 × 3 = 21
21 × 4 = 84
Option 1) (5, 45, 180):
5 × 3 = 15 (Does not match 45)
45 × 4 = 180 (Matches the third number but second number does not match)
Option 2) (15, 25, 180):
15 × 3 = 45 (Does not match 25)
25 × 4 = 100 (Does not match 180)
Option 3) (15, 45, 180):
15 × 3 = 45
45 × 4 = 180
Only Option 3 satisfies both conditions.
Option 4) (15, 45, 170):
15 × 3 = 45
45 × 4 = 180 (Does not match 170)
Therefore, the correct answer is option 3) (15, 45, 180).
