What would replace # in the sets ? [ {5,120,3},{9,630,5},{9,810, #} ] (A) 8 (B) 7 C. 6
What would replace # in the sets? ({5,120,3},{9,630,5},{9,810,#})
To solve this, let’s examine the pattern in the given sets. We have:
- ({5,120,3})
- ({9,630,5})
- ({9,810,#})
Let’s look for a relationship between the numbers. Observe that:
- In the first set: (5 \times 24 = 120) and (5 - 2 = 3)
- In the second set: (9 \times 70 = 630) and (9 - 4 = 5)
Now, let’s apply the same pattern to the third set:
- The multiplication step: (9 \times 90 = 810)
- For subtraction: We have (9 - 2 = 7)
So, the number replacing (#) should be 7.
Summary: The number that replaces (#) is 7. Option B is correct.
